What if Atomic Heart wasn’t just a game, but the start of a whole chaotic universe? The Cube is trying to be exactly that. Revealed at Summer Game Fest, this new MMO shooter takes the strange sci-fi world of Atomic Heart and spins it into something even weirder: a live-service game set inside a constantly shifting superstructure.
Players are dropped into The Cube, a colossal building that warps and reconfigures itself in real time. Floors flip, walls rotate, and combat arenas reshape while you’re still inside them. You’re not just here to survive—there’s a goal. According to the developers, solving the “central equation” hidden within The Cube is the key to stopping global collapse.
The gameplay is built around fast movement, weapon skills, and progression. You’ll be customizing gear and upgrading tools as you fight alongside (or against) other players. While it’s being called an MMO shooter, it leans into experimental design. The Cube isn’t static—each session might change the layout, the rules, or even the team compositions depending on the map shifts.
Behind the scenes, the game is using a new rendering system that lets thousands of moving parts stay synced across online matches. The studio claims this lets them build destructible, dynamic environments that actually react to every player—not just pre-scripted sequences.
The Cube is coming to PC, PlayStation 5, and Xbox Series X|S. No launch date yet, and details on monetization or structure are still under wraps. But the tech ambition is there, and for fans of Atomic Heart‘s strange tone and violent creativity, this could be one of the most unpredictable online shooters in years.
