Developer Saber Interactive has kept the momentum going with regular updates that add new material to the game’s story, PvE, and PvP modes. Recent updates have included new cosmetics, enemy types, and a redesigned perk system, while the March 2025 hotfix 6.2 improved gameplay balance and laid the groundwork for the huge 7.0 release. Now, all eyes are on the highly anticipated Update 8, which is set to be released on June 26, 2025, and promises to enhance the experience with new DLC and the addition of a thrilling game mode. Throughout 2025, players have benefited from additions such as the Salamander Champion skin, new PvE objectives, and a more difficult Absolute difficulty mode, as well as additional Battle Barge features like the Datavault for lore enthusiasts. Update 8 will provide exclusive DLC such as Blood Angels and White Scars cosmetic packs, as well as a rebalanced Absolute difficulty for die-hard players. It has also been announced that the same update will bring a new game mode that lets you battle an endless, glorious wave of Tyranids. Space Marine 2’s update 8 will bring Siege Mode to let you battle Tyranids like never before The upcoming Siege Mode in Warhammer 40,000: Space Marine 2, which will be available on June 26, 2025, delivers an exciting new PvE experience in which players face relentless waves of Tyranids and Chaos armies. This free upgrade will put even the most experienced Ultramarines to the test with its ruthless, survival-driven gameplay. Slay Tyranids in Siege Mode with your friends. Image by VideoGamer. Siege Mode, set in the rainforest world of Kadaku, is a three-player co-op mode in which players defend an Imperial citadel against fiercer enemy hordes. The goal is simple yet punishing: hold your ground for as long as possible, knowing that survival is fleeting but glory is eternal. The mode pits players against “seemingly endless” waves of Tyranids, using Saber Interactive’s swarm technology to generate chaotic, high-intensity fights. Expect to face familiar foes like Tyranid Gaunts in ranged combat, as well as harder enemies like Tyranid Warriors that require precise melee techniques, parries, and dodges. The game incorporates Space Marine 2’s existing progression system, letting players gain points for upgrades and reinforcements, which improve their loadouts and abilities as the waves escalate. The Biovore, a new Extremis-level Tyranid with a destructive biological cannon and melee abilities, offers a new layer of difficulty. Siege Mode, which will be available for testing on the Public Test Server (PC/Steam) beginning June 4, 2025, claims to reward teamwork and strategy, with players balancing armor regeneration through executions and health recovery via medkits.
