Mundfish used Summer Game Fest 2025 to announce Atomic Heart 2, a sequel to its hit alt-history Soviet FPS. Why are we covering it then? Well, this time, it’s going heavier on the RPG side.
In a first-look trailer, Atomic Heart 2 was introduced to the dulcet tones of Freddy Mercury in Queen’s Don’t Stop Me Now. There are surfing robots, a clearly bigger open world, and even more crazy powers to chuck machines about with.

Atomic Heart 2 is a spiritual sequel to the 2023 original and has been made with Unreal Engine 5. The original game depicted the unstoppable course of technology, along with secret experiments that gave rise to mutant creatures, terrifying machines, and superpowered robots—all suddenly rebelling against their creators. Only you can stop them and find out what lies behind the idealized world.
Here’s what Mundfish says about its latest game.
Atomic Heart 2 is an action-adventure role-playing game set in a living world, rich with possibilities and a heavy emphasis on the story, role-playing elements, and player freedom. The sequel to Atomic Heart relates new events unfolding in the retrofuturistic universe of an alternate history. This time, the action takes place on a global scale.
The original game had its issues, but there was no denying it stood out from the crowd of shooters. A sequel felt inevitable, and Mundfish is clearly pouring a lot into making Atomic Heart 2 a bigger, better, more ambitious outing.
