When asked about the ‘expanded RPG system’ that was announced for Atomic Heart 2, Bagratuni spoke about giving players deeper skill trees, with options for more varied progression paths. He also spoke about the “living world” of Atomic Heart 2, which will provide players with more reactivity to their actions.

“Yes, we’re introducing a more expanded RPG layer in Atomic Heart 2, but we’re doing it the Mundfish way – integrated into the world and the experience, not layered on top just for complexity’s sake,” said Bagratuni. “The ‘living world’ means that we want the world to feel less like a backdrop and more like a responsive, evolving system. But let’s not get ahead of ourselves – we will share more information when we are ready.”

“As for the RPG elements – we are aiming for deeper weapon customization, skill trees, and progression paths that allow players to shape their playstyle much more than before. When we talk about “various activities,” we mean things that reward curiosity: things to do between the main missions. But always in service of the core experience – we’re not turning it into a checklist-style open-world game. Everything still has that handcrafted, surreal tone fans expect.”

As for the game allowing players to make choices that would have direct consequence, Bagratuni spoke about how Atomic Heart 2 will allow players to “influence how certain events or missions unfold”. However, when it came to providing more details, he wanted to maintain some surprises for when the game comes out.

“Without giving too much away, we can say that Atomic Heart 2 will offer players more agency than before,” said Bagratuni. “Choices do matter, and your actions can influence how certain events or missions unfold. As for companions… that’s a tricky one to answer without spoilers. Let’s just say: you won’t be entirely alone.”

Atomic Heart 2 was unveiled earlier this month. Much like its predecessor, the upcoming title will once again be a first-person shooter. While no release window has been confirmed as of yet, Mundfish has confirmed that Atomic Heart 2 will be coming to PC and consoles.

The sequel is being developed using Unreal Engine 5, and the studio has previously described it as being more of a spiritual successor to Atomic Heart. The title will also feature Agent P-3 – Major Sergey Nechayev. However, what his presence means in terms of the story is yet to be explained.

Along with Atomic Heart 2, Mundfish has also unveiled an MMO shooter set in the same universe, dubbed The Cube. The title, announced at Summer Games Fest 2025, has a story that revolves around a mysterious floating structure known as the cube. While not too many details have been confirmed so far, players will apparently be trying to figure out the mysteries behind this giant cube.

Developed on Unreal Engine 5, it’s described as a spiritual successor to the first game, taking place on a global scale. There’s a greater emphasis on role-playing mechanics, and based on the trailer, new mechanics include a greater variety of vehicles, a glider, and many more new locations. Major Sergey Nechayev, known as Agent P-3, seemingly returns, but his role remains to be seen.

Stay tuned for further updates, which may take some time, especially given the first game’s lengthy development cycle. The first game is available for Xbox One, Xbox Series X/S, PlayStation 4, PlayStation 5, and PC. Check out our review here. It’s seen the release of several post-launch story DLC packs, further building on each ending while adding new weapons and locations to explore.
