Developer Mundfish is looking to expand Atomic Heart from a game to a franchise, and it’s doing so with not one but two new games. A full sequel, Atomic Heart 2, is on the way, alongside a more experimental multiplayer title with a reality-bending twist called The Cube.

Announced during Summer Game Fest and taking place after the first game–which was set in a retro-futuristic 1950s Soviet Union–Atomic Heart 2 will begin with the “world on the brink of collapse,” and it will see players head to more diverse locations. Mundfish says the story is now on “a global scale,” but it’s unclear just where we’ll actually be going.

Like the first game, there will be role-playing elements, which will be deeper this time around, as well as a dual-wielding combat system that will let players combine glove abilities (special tech-based attacks) with melee weapons and guns. It’s here where the studio’s BioShock influence is perhaps most clear, letting players find their ideal combination as they blast away at machines.

No release window was given for Atomic Heart 2, but it’s not the only Atomic Heart game on the way. Mundfish also revealed The Cube, an MMO spin-off that takes place after the first game.

“Several years after the events of Atomic Heart, the world stands on the brink of a new threat,” reads a line in the official announcement. “A mysterious giant levitating structure known as The Cube has become the epicenter of increasingly dangerous phenomena, and in order to save humanity, players must plunge deep into its secrets–and survive.”

The Cube (the structure) is more than meets the eye, with an “equation” hidden inside that can drastically alter reality. Failure to solve the equation will mean the destruction of the human race.

The game’s environments will constantly change, with “rows and edges” appearing and new enemies popping up, and hidden quests are scattered throughout the world. There will also be “persistent progression” that won’t be halted by “failure,” though Mundfish didn’t clarify exactly what that means.

Like Atomic Heart 2, The Cube doesn’t have a release window yet. Both games are coming to consoles as well as PC.
