Set in a giant, levitating, ever-shifting megastructure, The Cube blends tactical combat, deep RPG progression, and chaotic exploration, all powered by Mundfish’s proprietary Split-Rendering tech that redefines real-time motion in multiplayer worlds.

Several years after the events of Atomic Heart, the world stands on the brink of a new threat. 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.

On the surface, it’s a geometrically perfect object, and in truth it’s an anomalous, shifting place swarming with vicious enemies. But most terrifying of all is the equation hidden at the Cube’s core, capable of altering the laws of reality. Deciphering the equation can save humanity; failing to do so means extinction.

Can you survive another turn?

“At Mundfish, we were the first in the industry to implement a technology that allows thousands of objects to move and rotate simultaneously across massive stretches of terrain — online and in real time. No other game has ever done this before.” shared Robert Bagratuni, Founder and CEO of Mundfish. He continues, “This became possible thanks to our innovative proprietary split-rendering system, which redefines how motion is handled in interactive environments. The technology delivers maximum performance even under extreme load. In The Cube, physics, ballistics, and gravity feel completely natural — but under the hood, it’s powered by rocket science. The system enables seamless transitions, precise object tracking, and synchronized multiplayer in a living, ever-evolving world. It’s a true technological breakthrough.”
