Developer Rebellion has released a new trailer for upcoming survival investigative game Atomfall. The trailer showcases some of the games features, while also giving us a look at its world and some of the characters players will get to interact with. Check out the trailer below.The trailer emphasises the investigative aspects of Atomfall quite a bit, prompting players to investigate the games mysteries by searching, scavenging, and uncovering secrets. The trailer emphasises the danger players will face against the titles various enemy factions.Survival is also core part of Atomfall, of course, and players will have to sneak their way around various enemies while also making sure that they get enough supplies to get by.Earlier this week, lead designer Ben Fisher revealed that Atomfall had to go through several iterations during development before the studio was able to land on something it was happy with. Fisher spoke about how plans made before development dont always work, and that the developers had to work in layers to experiment and iterate.In the case of Atomfall, we were doing something so experimental in so many different ways., said Fisher in an interview. We had to work in layers instead and kind of iterate the game over time.Fisher also spoke about the level of stress experienced by the studio when it came to things not going as planned during development. This is because, while plans can be made, the realities of game development will often need these plans to be drastically altered.So youd have to approach any piece of design, any piece of content, bearing in mind that you dont know if thats the right answer, he said. Its your best guess so far, but youll only find out once its actually in context. You absolutely have to leave room for iteration. But you also need to do the work in a way that allows you to iterate. That doesnt come for free.In another interview from January, art director Ryan Greene spoke about how investigation would play a big role in Atomfall. He also revealed that the game doesnt even have a standard quest system. Players are instead expected to set out into the world and figure out their own leads for investigations.Right from the outset, you can do whatever you want. You can follow whatever lines of investigation that you want. Now, given that youll be poorly equipped, some choices may lead to bad results, said Greene.Greene also emphasised the freedom that players would have in Atomfall. Among other things, players can make friends with various NPCs by bartering with traders or making smart choices. On the other hand, players are also free to kill just about anyone while still being able to complete the games story.Atomfall is coming to PC, PS4, PS5, Xbox One and Xbox Series X/S on March 27. It is also available for pre-order. For more details, check out our coverage of the Deluxe Edition that also gives players 3 days of advanced access to the title.
