Atomic Heart 2 is currently in development at Mundfish, as shared today in an announcement at Summer Game Fest. Additionally, Mundfish also revealed The CUBE, a new multiplayer RPG shooter set in the Atomic Heart universe.
In a new trailer shown today, we got our first look at Atomic Heart 2, which is currently being worked on for both PC and console. Like its predecessor, it's an action-adventure FPS with RPG systems set in a retrofuturistic alternate-history. In a world intended to be a utopia for humans and their robot servants, advanced robotics and AI have gone rogue and torn society apart. Just before it all crumbles for good, the player steps in to stop the utter collapse of humanity.
As for The CUBE, it's set in the same universe as Atomic Heart, but takes place several years later in...well, a giant floating cube. The titular Cube's appearance has precipitated a number of strange and upsetting events, and players must head inside to discover the truth of what it really is and save humanity from its threat. The CUBE is a multiplayer RPG shooter planned for PC and consoles.
The first Atomic Heart launched in 2023 to an 8/10 review from IGN: "Atomic Heart is a deeply ambitious, highly imaginative, and consistently impressive atompunk-inspired attempt at picking up where the likes of BioShock left off – something it’s done with a lot of success," we wrote in that review.
Just last week, developer Mundfish revealed that Atomic Heart had surpassed 10 million players. The game has had multiple DLC releases since launch, and has one more still in development.
