The best roguelike games offer a serious but rewarding commitment, inviting you to lose time and time again until you reach new heights. And then you get to repeat the process while retaining knowledge that shapes your future sessions, improving your skills with each subsequent run.The best roguelike games follow the philosophy of randomizing existing game elements and providing a different experience every time you start a new run, with the condition that a game over screen means restarting from scratch. The roguelite distinction is similar, but it involves permanent progression, be it in the form of story, unlockable paths, items, and so on.Our selection of the best roguelike games has something for every player, regardless of platform and subgenre of choice. Our picks intersect with rhythm, deckbuilding, platforming, puzzle, and shooter games, to name a few. The roguelike and roguelite genres keep gaining more ground as pillars for design choices, meaning that some of the games on this list will ring familiar with the selections in our best PS5 games and best PC game lists. You'll also find some overlap with our recommendations for the best indie games to play right now.As the middle of 2025 draws near, choosing the best roguelike games becomes tougher with each passing day. The likes of Nuclear Throne, The Binding of Isaac, and Enter the Gungeon progressively marked their place in the genre years ago. Now, roguelikes and roguelites are in abundance, with game developers coming up with novel spins and pushing the genre forward.Whether you're looking for something more traditional or a unique take on a genre that is brimming with creativity, our best roguelike games list is bound to add a few new experiences to have on your radar. BalatroDeveloper: LocalThunkRelease Date: February 20, 2024Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, Android, iOS, PCIf you've seen your loved ones spending way too much time on their phones during the past year, it's likely due to LocalThunk's engrossing take on poker. Balatro is deceptively simple: Look at your hand, think of the combination that will net you the most points, and see the numbers go up.As you slowly make your way to tougher levels, gaining additional cards that multiply said score while granting an array of often absurd bonuses, you'll immediately understand the appeal. Balatro is not about poker, nor is it just a roguelike. It's a numbers game where you can rig the rules in your favor. Its challenges are hypnotizing, but once you achieve victory for the first time, it'll take you a while to play anything else. See at Amazon Pacific DriveDeveloper: Ironwood StudiosRelease Date: February 22, 2024Platforms: PlayStation 5, PCPacific Drive is not technically a roguelite, even if it shares quite a few similarities in how you navigate its world, picking up key items and tackling objectives as you escape from weather anomalies from the inside of your car. The Endless Expeditions update, however, does push the game toward that direction.Released on April 3 of this year, Expeditions takes you outside of the campaign and into a randomized map with modifiers and rewards, the latter including cosmetics and unique tools. The trick is that you won't be able to stock up on resources, as you're forced to scavenge and build your inventory from scratch each time.Expeditions only end once you've collected enough anchors on a map. The longer this takes, however, the harder the task will become, with anomalies gearing up in difficulty. If you're looking for an extra challenge or an interesting twist on the Pacific Drive formula, Expeditions is the answer.Fanatical and GameSpot are both owned by Fandom. See at Fanatical Dead CellsDeveloper: Motion TwinRelease Date: August 6, 2018Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, Android, iOS, PCDead Cells is one of the pioneers of the new wave of roguelites of the past few years. Ever since its conception, developer Motion Twin set out to build an ambitious foundation--prioritizing a breakneck rhythm and flow in movement and attacks, rewarding fast reflexes and improvisation on the spot.The team continued to work on the game over the years, delivering a total of 35 major updates, expanding and ironing out possibly every element inside out. If at some point you think the base game doesn't have enough to offer, there are five DLCs (one of them free), including the Return to Castlevania expansion. As it stands, there might never be another game like Dead Cells, and that's okay. We'll still be playing it for years to come, while also witnessing the team trying out new ideas, such as the co-op roguelite Windblown, which is an early access game to watch. See at Fanatical Deep Rock Galactic: SurvivorDeveloper: Funday GamesRelease Date: February 14, 2024Platforms: PCIf you're a Left 4 Dead 2 fan, chances are that you've heard of Deep Rock Galactic, which takes the structure of the zombie-driven shooter and takes it in a different direction, featuring dwarves in space, alien monsters, and destructible environments. Deep Rock Galactic: Survivor, however, takes things even further.Released in Steam early access back on February 14, 2024, you're taken onto increasingly harder levels where your dwarf of choice attacks automatically. The Survivor-like is presented in a top-down perspective, with the mining mechanic taking center stage to unlock upgrades during runs and improve your chances.There have been four sizable updates, but even in its infancy, developer Funday Games struck gold when mining for resources. The combination of its existing setting with the roguelike genre is an enticing one. See at Steam Hades 2Developer: Supergiant GamesRelease Date: May 6, 2024Platforms: PCDeveloper Supergiant Games has famously never done sequels before--until Hades 2. The sequel follows the events of the first game, in which Zagreus, son of the Greek god of the underworld, fought his way to the surface. Now, his sister Melinöe is tasked with defeating Chronos, the god of time itself, who's posing a threat unknown to everyone to this point.The roguelite is similar in nature to its predecessor, advancing the story with each victorious or failed run, gradually uncovering layer upon layer of new characters, powers to combine and grow stronger with, and even more features to further customize your experience. Hades 2 is still in early access, but there's a ridiculous amount of story and challenges to go through. Plus, the sequel is one of the first games confirmed for the Nintendo Switch 2. The 1.0 release date is yet to be confirmed, but Supergiant is targeting 2025. See at Steam Darkest Dungeon 2Developer: Red Hook StudiosRelease Date: May 8, 2024Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, PCDarkest Dungeon 2 entered early access in October 2021, with the full launch taking place on May 8. It had a tall order--surpassing the inimitable Darkest Dungeon, a tough roguelike centered around stress as a mechanic, with characters being driven mad or, on occasion, becoming inspired by the embrace of darkness and presence of heinous monsters.The sequel moves away from the structure of its predecessor, where you explored different biomes while managing resources and upgrading a home base. Now, it follows a structure similar to modern roguelite conventions, where you choose from different paths that are labeled with the rewards and challenges awaiting on the roads.While the combat shares some similarities, many new features shake up previous foundations, from playable origin stories for each hero to the affinity system, which takes the stress mechanic of the first game and adds a communal element to it by leading to different relationship archetypes between party members. Despite the change in presentation with more bells and whistles, Darkest Dungeon 2 retains the spirit of the first game--it's a visceral, tough-as-nails adventure that demands patience to overcome. See at Fanatical Rogue Legacy 2Developer: Cellar Door GamesRelease Date: April 28, 2022Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, PCWhen the original Rogue Legacy launched in 2013, its combination of metroidvania with roguelite elements was already promising. Yet, it pushed things further with a genius feature where, each time you die, one of your children succeeds you. The trick? Everybody has unique traits, from gigantism and baldness to color blindness and dyslexia, which would have gameplay impacts from the beneficial to the hilarious.Rogue Legacy 2 pushes the novelty with even more traits and classes, including a bard and a dragon lancer. The metroidvania aspect has also been improved with the addition of unique items that permanently unlock abilities to further explore the world and unveil its secrets. It's a sequel that successfully ticks every box a sequel must, and does so with a familiar grace and humor that still has a lot to offer over a decade later. See at Steam Spelunky 2Developer: Mossmouth and BlitWorksRelease Date: September 29, 2020Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, PCSpelunky is the classic go-to recommendation for a roguelike with ironclad design. The platformer with an Indiana Jones spirit made for one of the most challenging roguelites out there, requiring patience and the willingness to study every possible enemy pattern, trap, and miscalculation that can end your run, and then memorize it all for the next attempt.Spelunky 2 is a showcase of refinement upon refinement. Sure, it's touted with a bigger world with new areas to study, multiple routes to find and take advantage of, and an assortment of features meant to subvert long-standing fans' expectations. The sequel's greatest trick, however, is once again proving that meticulously thought design can elevate good ideas to admirable heights. The only way to improve is to keep trying, over and over, until surpassing the obstacles in your way becomes second nature. And then you get to do it all over again in the following area. See at Steam Slay the SpireDeveloper: Mega CritRelease Date: January 23, 2019Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, Android, iOS, PCDeck-building has become a popular marriage candidate for roguelites, and Slay the Spire might be one of the games responsible for its popularity. The premise is simple: You pick a character who has a predefined card deck and jump into a procedurally generated run. The rewards, obstacles, and challenges roaming your chosen paths are always different, demanding different strategies.As you make your way through a game session, you'll collect more cards for your deck, slowly customizing the options available to fit different playstyles and adapt yourself to the danger at hand. Do you invest in dealing as much damage as possible, neglecting your defense? Do you try to come up with different synergies to create a jack-of-all-trades card deck? There's always something to learn and discover, and the number of combinations available to experiment with is seducingly daunting. The best part? There's a sequel in the works, slated for 2025. See at Steam Risk of Rain 2Developer: Hopoo GamesRelease Date: August 11, 2020Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, PCRisk of Rain 2 is one of the few roguelites that explored the idea of taking the often pixel art, 2D-driven presentations of the genre and experimenting with 3D instead. Taking the elements that made its predecessor great, from enemy design to the different survivors you control, the change of perspective led to a breath of fresh air in the genre, and one of the most entertaining online games out there.The 1.0 release on August 11, 2020 has been followed up with hefty updates and paid DLC since. You can spend hours just fooling around with friends and seeing how far you can go. Once you get invested in the game's most intricate secrets and mechanics, however, you'll find out that the thrill comes down to becoming an unstoppable force challenged by a dynamic difficulty meter that's constantly keeping you on your toes. The use of 3D, then, isn't a mere novelty--it literally shines a new light on what roguelites can achieve when looked at from a different perspective, adding a different sense of movement and scale to the usual roguelite chaos. See at Steam Crypt of the NecrodancerDeveloper: Brace Yourself GamesRelease Date: April 23, 2015Platforms: PlayStation 4, Xbox One, Nintendo Switch, Android, iOS, PCCrypt of the Necrodancer might be one of the oldest picks of our best roguelike games list, but the reason is simple: No other roguelite has managed to combine the genre conventions with the mechanics of a rhythm game to such success. Every movement and action in the game is tied to the beat of the soundtrack blasting in the background.Enemies have different patterns that you must learn, all while carefully moving on tiles as if you were tapping the floor with your foot following a song. Even if you're not rhythm game savvy, the mix of both genres is accommodating enough to make you a believer--right until you meet a dragon for the first time, that is. After the original release, Cadence of Hyrule followed up on the concept, with the studio collaborating with Nintendo for a different take on The Legend of Zelda. But Crypt of the Necrodancer remains a worthy rogue classic. See at Steam Into the BreachDeveloper: Subset GamesRelease Date: February 27, 2018Platforms: Nintendo Switch, Android, iOS, PCThe alien invasion grows in numbers. You must assemble a squad of a handful of units and try to beat the odds. When you inevitably meet your demise, the last person standing creates a rift and travels to a different timeline. Time to start again.Into the Breach has a steep learning curve. Its design conventions, however, make it worth the effort to learn how to best use the space given to you and how your units can counterattack the alien push. The game is clear about the consequences of your movements on each map grid--whether or not you'll be able to land an attack, if one of your mechs will be caught in a tidal wave or an enemy projectile, and so on.Often, playing the strategy roguelike feels like a series of elaborate board games, where you carefully move pieces and spend your time thinking of the best possible plan. When it all comes together, the satisfaction is unparalleled. But even when you fail and you're sent to another timeline to commence anew, there's a thrill in knowing that next time might be the one if you take the time to analyze your movements and execute with care.Into the Breach is also the rare game to receive a 10/10 from GameSpot. See at Steam Loop HeroDeveloper: Four QuartersRelease Date: March 4, 2021Platforms: Xbox One, Xbox Series X|S, Nintendo Switch, Android, iOS, PCThe concept of loops and the repetitive nature of roguelites are a natural pairing. Loop Hero not only understands it, but extends it further by turning you into a dungeon master of sorts. You're given the choice of a hero and a map layout, as well as a deck of cards. You can place different types of terrain and structures, each having its own pros and cons. But you also need to place enemies, slowly making each loop--where the character walks a full cycle of the map--more intricate to navigate.The randomized nature of roguelites is heightened by giving you agency over the dangers that your hero will have to overcome. With a large number of unlockables to pursue after each session, as well as a captivating presentation, Loop Hero is one of the most inventive roguelites out there. See at Fanatical ReturnalDeveloper: HousemarqueRelease Date: April 30, 2021Platforms: PlayStation 5, PCHousemarque's expertise lies in games with an arcade nature, from Resogun to Nex Machina. At first glance, Returnal seems different--its presentation is powered by a level of production that screams AAA game. Initially introduced as a PlayStation 5 exclusive, the third-person shooter makes an interesting use of the roguelite concept, intertwining story events with each death. Similarly to Hades, meeting your demise rarely means taking a step back.Don't let its prestigious look deceive you, though--Returnal is the living proof of a modern arcade game, taking cues from the bullet hell genre. This means that you must be in constant movement, carefully timing dodges and narrow jumps to avoid a barrage of projectiles coming your way from all directions. A sequel is slated for 2026, but the first game deserves all of your attention. It's one of the best games in the PlayStation catalog, and a thrilling showcase of how a roguelite structure can inform a story, blending into one coexisting vehicle for a narrative that wouldn't work elsewhere. See at Fanatical Shogun ShowdownDeveloper: RoboatinoRelease Date: September 5, 2024Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, PCDeveloper Roboatino saw the synergy of roguelike and deck-building elements and decided to add turn-based combat to the mix. You command a lone hero who must take positioning and time into consideration to defeat multiple enemies and make it out unscathed.Using an inventive mechanic regarding the tiles you set foot on, Shogun Showdown hides a surprising level of depth, which you gradually uncover the more time you spend with it. You can upgrade and sacrifice different movements and skills in between battles, and as you die, you'll unlock new characters and attacks to experiment with. If you want to test the game's combat by yourself, there's a free prologue available on PC. See at Fanatical Blue PrinceDeveloper: DogubombRelease Date: April 10, 2025Platforms: PlayStation 5, Xbox Series X|S, PCIn Blue Prince, you're a fourteen-year-old boy next in line for an inheritance. The catch is that you first need to explore a manor that changes its inner structure each day, hiding access to the elusive room 46 somewhere within its bowels. Dogubomb's title is part puzzle game, part roguelite, part investigative game.When you start a new day, you're given a number of steps that you can take inside the manor. Upon interacting with a door, the game grants you a random selection of rooms, each containing a puzzle, resource items, or a clue to a larger mystery. Sometimes all three of them. The deeper you plunge into Blue Prince, the higher the chances of becoming engrossed by the sheer amount of layers upon layers of puzzles to solve. See at Fanatical Caves of QudDeveloper: Freehold GamesRelease Date: December 5, 2024Platforms: PCDevelopment for Caves of Qud began back in 2007, with the first public beta being released to the world in 2010. Then, after almost a decade in Steam early access, the game was fully launched on December 5, 2024. The science-fantasy roguelike is brimming with emergent stories, offering a deeply simulated world where you can shape the environment as you see fit, join one of over 70 factions, or simply get lost in the overwhelming number of possible actions and outcomes available.In Caves of Qud, every NPC and monster is as fully simulated as you, meaning that they all have their own skills, equipment, body parts, and levels. The body parts are important, as there are multiple mutations at play, from two heads to the power of cloning oneself. The sandbox nature and painstaking level of detail have added an unmatched identity to the roguelike over its long lifespan. Now, there's never been a better time to take a plunge and become a part of its labyrinthine systems and intricate synergies that are happening in the game without your input. See at Steam FTL: Faster Than LightDeveloper: Subset GamesRelease Date: September 14, 2021Platforms: iOS, PCCommanding a party is a classic go-to for roguelites. Being the captain of a spaceship where you must attend to your crew and rooms individually, however, is an idea that is still novel to this day. Before Into the Breach, developer Subset Games came up with a different adventure in outer space.Presented with randomly generated galaxies, you must pick different paths to warp to, taking care and managing your spaceship in your ventures. Everything from the state of the hull to the level of oxygen must be accounted for. While you might be lucky with the galaxy destinations you pick, your crew will inevitably have to confront other ships.It's during these moments that FTL: Faster Than Light showcases its exhilarating mix of mechanics, forcing you to act fast by putting up fires, deciding which rooms to open and which ones to close, and sending crew members to repair the ship, all while using similar strategies on the enemy at hand. There's no other game like FTL. See at Steam InscryptionDeveloper: Daniel Mullins GamesRelease Date: October 19, 2021Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, PCThe creator of the eerie Pony Island took a stab at the roguelike genre in 2021 with Inscryption. At first, you don't know where you are--all you can see is the inside of a dark cabin, and a strange figure that invites you to play a card game. The creepiness sets in more and more over time, as you use cards depicting animals that seem to be alive, trying to make progress in the game while also looking for an opportunity to try and figure out how to escape the cabin.Inscription has multiple twists that are best left as a secret. If you want a general indication of what to expect, however, this roguelike pulls you into an obscure setting that becomes darker the more time you spend with it, subverting existing genre conventions and familiar mechanics with a horror twist. See at Fanatical Dome KeeperDeveloper: BippinbitsRelease Date: September 27, 2022Platforms: PCDome Keeper is a great game for people who enjoy multitasking. As the name implies, you must protect a dome from enemy attacks. In order to do so, you must dig underneath the surface to search for resources and artifacts, which are used to choose upgrades and different ways to defend your base.Enemies won't just sit and wait, however. You only have a limited time to dig in between attack waves. Picking your upgrades carefully will make or break your chances of survival to gain another chance at plunging through the surface and build better defenses. Dome Keeper is an ambitious survival game that takes cue from roguelikes and tower defense games to create a different kind of challenge to overcome. See at Fanatical Monster TrainDeveloper: Shiny ShoeRelease Date: May 20, 2020Platforms: PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, iOS, PCMonster Train is the distant cousin of Slay the Spire. You're given a deck of cards that you slowly grow during runs, as well as different paths to choose from. The twist is how combat encounters are structured, turning elements like positioning and card strategies on their head.Whenever you face enemies, you're presented with a large vertical structure that has three play fields. You must carefully plan where to place your cards to defend the train's core. It's an idea that's pushed to its limit time and time again with the cards available and the ways in which enemies can also strategize around your defenses. Monster Train is a prime example of how much innovation is still in the genre. See at Fanatical Vampire SurvivorsDeveloper: PoncleRelease Date: October 20, 2022Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, Nintendo Switch, Android, iOS, PCTaking inspiration from a mobile game called Magic Survival, in which the main character attacked automatically without the player's input, developer Poncle leaned on a fascination for Castlevania's aesthetic to iterate on the concept. The simple idea led to an absurd amount of characters, levels, and items to unlock--including, of course, an official collaboration with Konami to include more than just indirect references to the Castlevania series.Playing a Vampire Survivors stage can last anything from 15 to 20 or 30 minutes--if you can survive long enough with the items you've acquired. Even if you fail, however, you're constantly unlocking items, characters, and stages to explore in subsequent runs. It's a game that's best described as a Pandora's Box equivalent. Especially considering the chaos that it will likely inflict on your schedule. See at Steam Hitman World of Assassination: Freelancer ModeDeveloper: IO InteractiveRelease Date: January 26, 2023Platforms: PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, PCThe Hitman series has always excelled in presenting puzzle boxes that double down as playgrounds to blend in, follow your target, and take them down in increasingly ridiculous ways. Freelancer Mode, introduced to Hitman World of Assassination on January 26, 2023, adds a different spin to the premise with a persistent and highly replayable experience.In this mode, targets are always random, and you're given access to different bonus objectives. Making use of a hub exclusive to Freelancer, Agent 47 must choose a crime syndicate to pursue, which sets the mood of the campaign, and then get started without any equipment or weapons. If you've already mastered the classic Hitman levels or you just want a different, ridiculously polished roguelike experience, Freelancer Mode is a distinct and ambitious take on the genre. Worth mentioning that Hitman World of Assassination is also slated to launch on Nintendo Switch 2. See at Steam InkboundDeveloper: Shiny ShoeRelease Date: April 9, 2024Platforms: PCFrom the makers of Monster Train comes Inkbound, a turn-based tactical roguelike that offers co-op, and synergies that are heightened by coordinating with others online. Players can move freely and act simultaneously in multiplayer, picking from eight different classes to try out different combinations.There's also a deck-building element of sorts involved in the vein of draftable abilities, upgrades, and an array of items to use in-game. It's an intriguing blend of genres that might take some time to get used to. Once things click, however, you and the rest of the party will be working in tandem to see how far you can push your strategies. See at Steam God of War Ragnarok: ValhallaDeveloper: Santa Monica StudiosRelease Date: December 12, 2023Platforms: PlayStation 4, PlayStation 5, PCGod of War Ragnarok is a behemoth of an action-RPG, featuring a lengthy campaign across open areas with side quests, collectibles, and dozens of corners to explore. If you're looking for a break from the main story or just want to try a new roguelite that elevates some of the game's strengths in a different structure, the free Valhalla DLC is a must play.Taking place after the events of the main story (although you can jump into it at any point from the main menu without worrying about spoilers of the main campaign), Valhalla has Kratos going through a series of punishing trials, which slowly serve as a therapy session of sorts as he reminiscences of the events that happened during the original trilogy of God of War games.The bite-sized rendition of combat encounters shines a different light on combat mechanics that you may already be familiar with. And, taking cues from the likes of Hades and Returnal, each death pushes the story forward in meaningful ways. Valhalla is a rare combination of genres that shouldn't work as well as they do, and it deserves your time before the next adventure of Kratos inevitably rolls in. See at Fanatical NoitaDeveloper: Nolla GamesRelease Date: October 15, 2020Platforms: PCAfter a short early access period in 2019, Noita was fully released in October 2020, and provided an escape from the horrors of that year with, well, more horrors. Its punishing difficulty and procedurally-generated worlds provide deep and engaging gameplay. Noita places you in the shoes of a wand-wielding alchemist navigating a deadly, destructible world. The seemingly simple pixel art style leads to complexity where water flows, acid burns, fire spreads, and cave-ins can be triggered by a single misplaced explosive.Unlike many roguelikes that focus on stat-based progression, Noita appeals to player creativity and experimentation. The game's wand crafting system is a particular highlight, allowing you to mix and match spells, modifiers, and triggers to create devastating effects or strange contraptions that alter the way the game plays with every decision. The fun of Noita is learning how to break it in delightfully chaotic ways. This customization means each run feels unique, not just because of the randomized levels, but because the tools at your disposal and the way you choose to implement them define each playthrough. Noita is deeper than it first appears, with plenty of secrets and mysteries to uncover. Its expansive hidden world and lore begs to be uncovered, and the community engagement and conversation around it continues even half a decade on from its release. Experiment with fire, mess around with slime, and Noita will reward your curiosity. You'll find that, most of the time, death in Noita stems from your own creation, giving the game a cruel sense of irony and punishment. Despite that, or perhaps even because of that, Noita is a beautiful experience. See at Steam

Nature, Published online: 13 June 2025; doi:10.1038/d41586-025-01862-xEarth’s magnetic field seems to correlate with conditions that helped complex life to thrive — a discovery that could aid the search for life on distant exoplanets.

The nightmare was real, the situation was not.Revenge of the Savage Planet, an adventure spread across a number of distant — and quite savage! — planets, invites nonlinear exploration. To complete its missions and discover all of its secrets, you must leap into an unknown where the otherworldly flora, fauna, and even the inorganic material are primed to kill you. So, shortly after assembling an underwater scooter that allowed my robot sidekick to whisk me through the depths of alien oceans, I descended into a series of caverns under the Zenithian Rift to see what was going on down there. The specters of death I encountered below weren’t even designed to haunt me.In Raccoon Logic’s sequel to Journey to the Savage Planet, players are tasked with scanning every object in every nook and cranny to assemble an exhaustive log of materials located on each planet. At first, the task is a walk in the (overgrown killer) park: find a tree, scan a tree. Find a slobbering beastie, scan a slobbering beastie. But a counter on the map charting your scannables becomes the most daunting subtask — can I really find every single micro scannable? I found myself longing after completing the core missions. To really 100% this, there was even more reason to venture into the most uninviting spaces, including a dark underwater cave on Zenithian Rift that absolutely did not look like it contained any scannable items. But I couldn’t not go in there.It took about two seconds for me to realize… I had made a horrible mistake. While the cave was easily accessible from the water, there were no enemy or collectible breadcrumbs to suggest this was a place the folks at Raccoon Logic intended for me to. I was lured in by curiosity, but the joy of discovery in Revenge of the Savage Planet got the best of me. Now I was stuck. I had stumbled into a graphical anomaly, an in-game black hole that had an entrance but no apparent exit. In Revenge of the Savage Planet, you can’t beam back to starting locations on the fly or off yourself in order to respawn from your last save. In a clever but likely divisive design choice, the game forces you to navigate to transporters spread across the worlds in order to beam off to your next desired location, which forces traversal and new encounters. But it meant that while bumbling around in the dark, hoping to find a way out of my watery grave, I couldn’t simply die and move on. I was actually trapped, and in a scenario I haven’t experienced in quite some time, feeling IRL like I was actually trapped.I already don’t do well with underwater levels out of an intense fear of drowning. Luckily for me, most games will throw me the lifeline of a visual countdown to illustrate oxygen levels, ensuring (1) I surface in time and (2) I don’t hyperventilate over the stress of surfacing in time. Revenge of the Savage Planet doesn’t need that because there’s no punishment for enjoying the waters; you’re already in a spacesuit and the challenges you encounter via underwater scooter require a bunch of time-intensive back and forth. Doing it all on limited air would simply not be fun. But that meant, stuck in this tight underwater cave, I would never die. I was in limbo. Or maybe I was in hell.I spent far too long searching for a route out. Streaks of light bled in from a theoretical escape that I could never reach — any time I thought I was close, I bumped into a new rock and found myself jetting in the opposite direction. Not since I watched The Rescue, the riveting-yet-terrifying documentary about the team of divers who squeezed through cave passageways to free 12 trapped Thai soccer players, had my apparent claustrophobia had its way with my nerves. I can’t quite explain why I pushed myself over the edge to find an in-game solution to this unintentional challenge, except to say that I really wanted to do a good job at Revenge of the Savage Planet.Most glitches are considered errors by programmers, annoyances by players, and occasionally shortcuts for the speedrunner crowd. Revenge of the Savage Planet’s death cave might fall into the first two categories, but it’s a harrowing experience I ultimately appreciated, a unique screw up that could only happen in a game. I have never felt truly trapped in a film, despite the best efforts of 3D stereoscopic effects and 4DX rumble seats. After finally rebooting Revenge of the Savage Planet, I had to give myself a few minutes to let my heart rate die down before I grabbed the controller. But I got right back to it. Sure, this was a glitch, but in a game where exploration is everything, leaping into a true unknown — one that the creators of the game clearly didn’t intend me to find — was its own form of success.Revenge of the Savage Planet is currently available for PC, Playstation, and Xbox, and it’s currently on Game Pass.See More:

We need to ask how nations will deal with this inevitability now, as more people start traveling off the planetBy Peter Cummings edited by Lee Billings SciePro/Science Photo Library/Getty ImagesIn 2012 NASA stealthily slipped a morgue into orbit.No press release.

Officially, it was called the Human Remains Containment Unit (HRCU). To the untrained eye it looked like a shipping bag for frozen cargo.

If they passed away on a spacecraft or space station, would their remains be cast off into orbit—or sent on an escape-velocity voyage to the interstellar void?NASA, it turns out, has begun working out most of these answers. And none too soon. Because the question itself is no longer if someone will die in space—but when.A Graying CorpsNo astronaut has ever died of natural causes off-world. In 1971 the three-man crew of the Soviet Soyuz 11 mission asphyxiated in space when their spacecraft depressurized shortly before its automated atmospheric reentry—but their deaths were only discovered once the spacecraft landed on Earth. Similarly, every U.S. spaceflight fatality to date has occurred within Earth’s atmosphere—under gravity, oxygen and a clear national jurisdiction. That matters, because it means every spaceflight mortality has played out in familiar territory.But planned missions are getting longer, with destinations beyond low-Earth orbit. And NASA’s astronaut corps is getting older. The average age now hovers around 50—an age bracket where natural death becomes statistically relevant, even for clean-living fitness buffs. Death in space is no longer a thought experiment. It’s a probability curve—and NASA knows it.In response, the agency is making subtle but decisive moves. The most recent astronaut selection cycle was extended—not only to boost intake but also to attract younger crew members capable of handling future long-duration missions.NASA’s Space MorgueIf someone were to die aboard the ISS today, their body would be placed in the HRCU, which would then be sealed and secured in a nonpressurized area to await eventual return to Earth.The HRCU itself is a modified version of a military-grade body bag designed to store human remains in hazardous environments. It integrates with refrigeration systems already aboard the ISS to slow decomposition and includes odor-control filters and moisture-absorbent linings, as well as reversed zippers for respectful access at the head. There are straps to secure the body in a seat for return, and patches for name tags and national flags.Cadaver tests conducted in 2019 at Sam Houston State University have proved the system durable. Some versions held for over 40 days before decomposition breached the barrier. NASA even drop-tested the bag from 19 feet to simulate a hard landing.But it’s never been used in space. And since no one yet knows how a body decomposes in true microgravity (or, for that matter, on the moon), no one can really say whether the HRCU would preserve tissue well enough for a forensic autopsy.This is a troubling knowledge gap, because in space, a death isn’t just a tragic loss—it’s also a vital data point. Was an astronaut’s demise from a fluke of their physiology, or an unavoidable stroke of cosmic bad luck—or was it instead a consequence of flaws in a space habitat’s myriad systems that might be found and fixed? Future lives may depend on understanding what went wrong, via a proper postmortem investigation.But there’s no medical examiner in orbit. So NASA trains its crews in something called the In-Mission Forensic Sample Collection protocol. The space agency’s astronauts may avoid talking about it, but they all have it memorized: Document everything, ideally with real-time guidance from NASA flight surgeons. Photograph the body. Collect blood and vitreous fluid, as well as hair and tissue samples. Only then can the remains be stowed in the HRCU.NASA has also prepared for death outside the station—on spacewalks, the moon or deep space missions. If a crew member perishes in vacuum but their remains are retrieved, the body is wrapped in a specially designed space shroud.The goal isn’t just a technical matter of preventing contamination. It’s psychological, too, as a way of preserving dignity. Of all the “firsts” any space agency hopes to achieve, the first-ever human corpse drifting into frame on a satellite feed is not among them.If a burial must occur—in lunar regolith or by jettisoning into solar orbit—the body will be dutifully tracked and cataloged, treated forevermore as a hallowed artifact of space history.Such gestures are also of relevance to NASA’s plans for off-world mourning; grief and memorial protocols are now part of official crew training. If a death occurs, surviving astronauts are tasked with holding a simple ceremony to honor the fallen—then to move on with their mission.Uncharted RealmsSo far we’ve only covered the “easy” questions. NASA and others are still grappling with harder ones.Consider the issue of authority over a death and mortal remains. On the ISS, it’s simple: the deceased astronaut’s home country retains jurisdiction. But that clarity fades as destinations grow more distant and the voyages more diverse: What really happens on space-agency missions to the moon, or to Mars? How might rules change for commercial or multinational spaceflights—or, for that matter, the private space stations and interplanetary settlements that are envisioned by Elon Musk, Jeff Bezos and other tech multibillionaires?NASA and its partners have started drafting frameworks, like the Artemis Accords—agreements signed by more than 50 nations to govern behavior in space. But even those don’t address many intimate details of death.What happens, for instance, if foul play is suspected?The Outer Space Treaty, a legal document drafted in 1967 under the United Nations that is humanity’s foundational set of rules for orbit and beyond, doesn’t say.Of course, not everything can be planned for in advance. And NASA has done an extraordinary job of keeping astronauts in orbit alive. But as more people venture into space, and as the frontier stretches to longer voyages and farther destinations, it becomes a statistical certainty that sooner or later someone won’t come home.When that happens, it won’t just be a tragedy. It will be a test. A test of our systems, our ethics and our ability to adapt to a new dimension of mortality. To some, NASA’s preparations for astronautical death may seem merely morbid, even silly—but that couldn’t be further from the truth.Space won’t care of course, whenever it claims more lives. But we will. And rising to that grim occasion with reverence, rigor and grace will define not just policy out in the great beyond—but what it means to be human there, too.

A Deadly Disease Is Eating Away at Caribbean Corals and Wreaking Havoc on Reefs. Could Probiotics Be the Solution? New research suggests the probiotic McH1-7 could help stop the spread of stony coral tissue loss disease among wild corals near Fort Lauderdale, Florida Scientists determined the most effective method of halting the disease was covering a coral colony with a weighted plastic bag, then injecting a seawater solution that contains the probiotic. They left the colony covered for two hours to allow the probiotic bacteria to colonize the coral. Hunter Noren Probiotics can be good for human health. Now, new research suggests they might also help protect coral reefs. A bacterial probiotic helped slow the advance of stony coral tissue loss disease—a fast-spreading and deadly condition—among wild corals in Florida, researchers report today in a new study published in the journal Frontiers in Marine Science. The probiotic may be a good alternative to antibiotics like amoxicillin, which temporarily curb the spread of the disease but must be reapplied frequently. In addition, scientists fear stony coral tissue loss disease may one day become resistant to these antibiotic treatments—just as “superbugs” that infect humans are building resistance to our own drugs. Antibiotics are meant to kill microorganisms, but probiotics are beneficial living microbes. The idea is that a probiotic can be incorporated into corals’ natural microbiomes, ideally offering them longer-lasting protection. First discovered in Florida in 2014, stony coral tissue loss disease attacks the soft tissue of more than 30 different species of coral. Without treatment, the disease eventually kills the corals, and their soft tissue falls off, revealing the white calcium carbonate skeleton below. In just weeks or months, it can devastate a whole colony. Stony coral tissue loss disease can be spread by fish that eat coral, as well as by boaters and divers who do not disinfect their gear. The condition has since expanded its range beyond Florida to reefs throughout the Caribbean. Several years ago, researchers looking at the great star coral (Montastraea cavernosa) discovered a probiotic called Pseudoalteromonas sp. strain McH1-7. Laboratory tests showed McH1-7 stopped or slowed the progression of stony coral tissue loss disease in infected corals. It also helped prevent the disease from spreading to healthy corals. But that was in the lab. Would McH1-7 be similarly effective in the ocean? Researchers were eager to find out, so they set up an experiment on a shallow reef off the coast of Fort Lauderdale. Study co-author Kelly Pitts, a research technician with the Smithsonian Marine Station, applies a paste containing the probiotic directly onto the disease lesion of an infected coral. Hunter Noren Experimenting with wild corals For the study, the scientists focused on 40 great star coral colonies that were showing symptoms of stony coral tissue loss disease. In one experimental condition, the researchers made a paste that contained McH1-7 and applied it directly onto the disease lesions. For comparison, they also applied the same paste, minus the probiotic, to some corals. In another condition, they covered infected coral colonies with weighted plastic bags, then filled the bags with seawater solutions made with and without McH1-7. They left the corals covered for two hours. “This created a little mini-aquarium that kept the probiotics around each coral colony,” says study co-author Valerie Paul, head scientist at the Smithsonian Marine Station at Fort Pierce, Florida, in a statement. The scientists completed all the treatments within the first 4.5 months of the project. Then, they returned periodically to gather tissue and mucus samples from the corals to measure changes to their microbiomes. Over the next 2.5 years, they took photos from a variety of different angles, which they then used to create 3D models that could track the disease’s progression. In the end, the results suggest covering the corals with plastic bags filled with the probiotic seawater solution was the most effective method. More than two years post-treatment, the colonies that received the probiotic bag had lost just 7 percent of their tissue, while colonies in the control bag condition faced 35 percent tissue loss. Scientists applied a probiotic paste directly to disease lesions on some corals. Kelly Pitts The probiotic paste, by contrast, appears to have made the situation worse: The corals that had the probiotic paste applied directly to their lesions lost more tissue than those treated with the control paste, which did not contain McH1-7. “We do not really know what is going on with the probiotic paste treatment,” Paul tells Smithsonian magazine in an email. But she has a few theories. It’s possible the high concentrations of McH1-7 contributed to localized hypoxia, or low-oxygen conditions that further harmed the already stressed corals, she says. Or, the probiotic could have changed the microbiome at the lesion site in some negative way. Another possibility is that McH1-7 produces antibiotics or other substances that were harmful at high concentrations. Amanda Alker, a marine microbiologist at the University of Rhode Island who was not involved with the study, wonders if this finding suggests McH1-7 is beneficial at specific dosages—a question future laboratory research might be able to answer, she tells Smithsonian magazine in an email. She’s also curious to know which specific molecular components of the probiotic are responsible for the increased tissue loss when applied as a paste. More broadly, Alker would like to see additional experiments validating the bag treatment method, but she says this “inventive” technique seems promising. “Their approach is a safer solution than antibiotic treatment methods that have been deployed to combat [stony coral tissue loss disease] in the field so far,” she says. “Further, this is a practical solution that could be implemented widely because it doesn’t require highly specialized equipment and has the ability to be used with any type of microbial solution.” Looking ahead to save reefs Probiotics are likely not a silver bullet for protecting corals. For one, researchers still don’t know exactly what causes stony coral tissue loss disease, which makes it difficult to determine how or why the probiotic works, Paul says. In addition, since the disease has spread to many different parts of the Caribbean, it might be challenging to use the bag treatment technique on all affected colonies. “We would need to develop better methods of deploying the probiotic through time release formulations or other ways to scale up treatments,” Paul says. “Right now, having divers swim around underwater with weighted bags is not a very scalable method.” The researchers have also conducted similar experiments on infected corals located farther south, in the Florida Keys. However, these tests have produced mixed results, probably because of regional differences in stony coral tissue loss disease. This is another hurdle scientists will likely need to overcome if they hope to expand the use of probiotics. “We probably need to develop different probiotics for different coral species and different regions of the Caribbean,” Paul says. Researchers returned to gather samples of tissues and mucus to see how the corals' microbiomes had changed. Hunter Noren Even so, scientists are heartened by the results of the experiments conducted near Fort Lauderdale. With more research, the findings suggest probiotics could be a promising tool for combatting the disease elsewhere. “Coral probiotics is a challenging field, because there are hundreds of different types of bacteria that associate with corals, and there are limitless experiments that need to be performed,” Amy Apprill, a marine chemist at Woods Hole Oceanographic Institution who was not involved with the research, tells Smithsonian magazine in an email. “These researchers made a major advance with their study by demonstrating the utility of whole colony treatment as well as the specific probiotic tested.” Apprill adds that, while antibiotics have been widely used to control stony coral tissue loss disease, scientists haven’t conducted much research to see how these treatments are affecting the plants and creatures that live nearby. “Using a naturally occurring bacterium for disease treatment may result in lessened impacts to other members of the coral reef ecosystem,” she says. Amid rising ocean temperatures, scientists expect to find even more diseased coral colonies in the future. Warmer waters may also allow other pathogens to thrive and proliferate. Against that backdrop, Apprill adds, probiotics and the different methods of applying them will be “major allies” in the fight to save coral reefs. Paul is also optimistic. Through research and field studies, she’s confident researchers will be able to develop interventions that can “help corals better survive changing environments and respond better to diseases and bleaching,” she says.

We may earn a commission from links on this page.In 2023, I decided to update my Apple Watch after consistently failing to wear my Series 4 for a number of years. I sold that one on Poshmark and began looking at newer models to find one with enough features to convince me to actually wear it. I opted to get a Series 8, although the Series 9 had just been released, as I was buying two: one for my mom and one for myself. As it turns out, that was a great decision.If you're searching for a new wearable or considering upgrading yours, you might also be wondering which of the older Apple Watch models is still useful today. My Series 8 is holding up beautifully three years after it was introduced, so I'm a big proponent of using older devices as long as possible. But not all Apple Watches will work as well as the Series 8 does in 2025. Don’t buy a watch Apple doesn’t support anymoreWe have to draw the line somewhere: Seven of Apple's watches are no longer supported, meaning they won't receive any software or security updates anymore. In addition, you run the risk that the watch will no longer be compatible with your iPhone or certain apps. In short, you shouldn't buy a watch that Apple doesn't support. That includes the following:Apple Watch Series 0Apple Watch Series 1Apple Watch Series 2Apple Watch Series 3Apple Watch Series 4Apple Watch Series 5Apple Watch SE (first-gen) While the company does currently support the Series 6, it is next in line to join this list. It's not clear when that will happen, but you can be sure it will. We'll see next week—when Apple reveals watchOS 26—whether the watch will be supported another year. If not, it'll be stuck on watchOS 11 for good.Performance and other generational Watch improvementsThere are considerations for older Apple Watch models that extend beyond their ability to simply run the latest operating system. With each generation, improvements are made in some form or another. For instance, the Series 4 introduced the ECG sensor, while the Series 6 introduced the blood oxygen sensor (though Apple had to disable the feature for the Series 9 and Ultra 2 in the U.S. due to a lawsuit). The Series 7 charges faster than its predecessors, and Apple has included fast charging on most watch models since (sorry, Apple Watch SE users).In general, each Apple Watch is faster than the last. Apple tends to put its newest S-Chip—the Apple Watch's processor—in its latest watch series. Simply put, a newer S-chip gives you a faster, more productive product. The Series 6 has an S6 chip, Series 7 has S7, and so on until you hit the Ultras. (The first-generation Ultra has an S8 chip like the Series 8, while the Ultra 2 has an S9 chip like the Series 9.)While there are some core features all currently supported watches share—like workout and swim tracking, sleep tracking, Apple Pay, ECG scanning, and the ability to read and respond to messages—newer models also each have some of their own special advancements and upgrades. Here's a brief list:The Series 7 introduced faster charging, a larger display, and more durable screen.The Series 8 brought temperature sensing, crash detection, and a low-power mode for conserving battery (as did the second-gen Apple Watch SE).The Series 9 debuted new gesture controls, on-device Siri access, more precise location tracking in Find My, and a display with double the brightness of the Series 8.The first-gen Apple Watch Ultra introduced a more durable titanium casing, custom shortcuts to apps and modes via the Action button, a depth gauge and water temperature sensor, more accurate GPS, a 36-hour battery life, and an emergency siren.The Apple Watch Ultra 2 introduced a display with a maximum brightness of 3,000 nits and on-device media playback. The Series 10 introduced the largest display available on a standard Apple Watch and faster charging. If you see a feature you absolutely need in a particular watch model, you'll have to spring for it. But if you just want something for core Apple Watch tasks, you can start to consider older options. Apple's watch comparison site can be a helpful tool for identifying different features among models. Battery degradation All tech degrades to some extent and the Apple Watch is no different—particularly when it comes to the battery. While there are ways to mitigate the problem, over time, the lithium-ion battery powering your wrist computer won't last as long as it used to. That might be a bigger issue than your watch's ability to download and support a new operating system. Apple's warranty doesn't cover batteries that wear down from normal use, and charges $99 for the repair, which you could instead put towards the purchase of a new watch. There is one exception: Battery service is free if you have AppleCare+ and your watch's battery holds less than 80% of its original capacity. You need to take your watch in to an Apple Store or service provider to have it tested. My watch was pre-owned, and while I have no way of knowing if it has its original battery, my battery life has not declined substantially in the two years I've been using it daily. I primarily use mine to track my workouts, vitals, and sleep, which means it's always running. I charge it while I'm in the shower and occasionally for a few minutes before bed, and that's about it. On an average day of constant notifications, mine lasts me a bit longer than the advertised 18-hour mark. Because I have little interest in the small improvements offered by the Series 9 and Series 10—like extra brightness, larger screen size, performance bumps, and advanced cycle tracking—the battery life is what would (or will) compel me to upgrade in the future, but for now, I have not noticed any problems. I asked my mom if she's noticed any battery degradation on hers, since I bought it at the same time and place as mine, and she said no. She uses hers to track walking workouts, talk on the phone, and monitor her sleep and vitals, too.Stick with the Series 7 or newerThoroughly consider which of the features on newer models are actually important to you before making any buying decision and, if you can, stay above a Series 7. The Series 6 is still functional, but, again, it's a matter of time until the company stops acknowledging that one completely. For now, I have been pleasantly surprised by how well my Series 8 has held up for two years. Its touchscreen has never faltered, the external buttons function perfectly, it syncs to all of my apps and devices with no problem, and it does exactly what I need it to do—which is to tell me how many steps I'm taking and how hard I'm exerting myself at the gym. If you're in the market for a smart watch, I see no reason that an older version shouldn't be considered, as long as it still runs the latest operating system. You can save a chunk of change by sourcing an older model from the resale or refurbished markets and put that money away for when Apple drops something super revolutionary in the wearable space. Apple doesn't sell anything below a Series 10 or SE directly anymore, so if you want a 6, 7, 8, or 9, you'll have to check the resale and refurbished markets. You'll definitely save some money that way (a new Series 10 starts at $399, though it can be found on sale, and the refurbished Series 8 I got is selling right now for $219).

June 2, 20253 min readThe World Isn’t Ready for the Mental Health Toll of Extreme HeatTemperatures are rising, and so are mental health risksBy Madhusree Mukerjee edited by Dean VisserA man walks with an umbrella to protect himself from the heat as a yellow alert is issued by the UK Health Security Agency (UKHSA) due to increasing temperatures in London, United Kingdom on June 25, 2024. Rasid Necati Aslim/Anadolu via Getty ImagesThe coming summer is forecast to be a scorcher across the U.S. And climate scientists predict that at least one of the next five years will beat 2024 as the hottest year ever recorded globally. As heat waves are getting more intense and prolonged, their effect on the mind and body are also becoming more dire. Children and older people, as well as those who work outdoors, are most at risk. So are those with mental health disorders.Heat waves are the single highest cause of weather-related deaths in the U.S., where an estimated 1,300 fatalities from heat stroke and other temperature-related complications occur every year. Even those who survive a period of extreme heat may suffer serious neurological or other mental-health-related disorders.A new study published in Current Environmental Health Reports finds that the world is startlingly unprepared to deal with the mental health consequences of climate change. Of 83 action plans for heat-related health problems that were reviewed for the study, fewer than a third acknowledged the mental health effects of extreme or prolonged high temperatures. And only a fifth of these plans outlined specific actions to deal with contingencies such as increased hospitalizations for mental health disorders.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

If a person doesn’t drink enough water when the weather is hot and dry, the body becomes dehydrated, the blood thickens, and the heart may not be able to pump enough oxygen to the brain. Additionally, the human brain burns up 20 percent of the body’s energy and therefore needs to dissipate heat efficiently. In hot and humid conditions, sweating cannot cool the body and brain enough. This can lead to heat exhaustion, which has symptoms such as weakness, dizziness and headaches and, in extreme cases, heat stroke—which can then trigger delirium and loss of consciousness. A significant fraction of heat stroke survivors suffer neurological complications.Exposure to extreme heat can also increase the risk of suicide and can worsen schizophrenia, epilepsy, anxiety, depression, substance use disorder, neurodegenerative disorders (such as Alzheimer’s disease) and negative emotions such as fear and anger. It may worsen sleep, which, in turn, can increase fatigue and impair cognition. Alcohol and recreational drugs, as well as certain medications used to treat mental illness, such as antidepressants, tranquilizers and antipsychotics, also appear to increase mental health vulnerability to heat.Studies find an increased risk of suicide and epileptic seizures during heat waves, as well as an increase in hospitalizations and emergency-room visits for mental health disorders. Heat can also disorient thinking, making people slow to realize that they need to seek shelter or help.Who is most at risk?The most vulnerable are those with existing mental health disorders. Disturbingly, prolonged heat waves also appear to worsen the risk among young children—and even the unborn—of developing mental health ailments in the future. Older people may also be particularly affected, such as by accelerated dementia and Alzheimer’s.At particular risk are vast populations around the world who live without air-conditioning, including poor or homeless people and those who work outdoors, such as on farms.What can be done?The authors of the new Current Environmental Health Reports study point to interventions at several levels to help communities and individuals most at risk of climate mental health impacts. These can include public awareness campaigns, such as warning people about the mental health risk of consuming alcohol or other drugs during heat waves. Other interventions include establishing community cooling shelters for heat emergencies and increasing monitoring of mental health patients during heat waves. Extreme heat is here to stay, at least for the foreseeable future. We need to prepare people and communities to reduce the risk of mental health emergencies.IF YOU NEED HELPIf you or someone you know is struggling or having thoughts of suicide, help is available.
