On 6 June 2025: The game was announced at the Summer Game Fest 2025 and will be an MMOFPS set in the Atomic Heart universe. The title, coming to PC and consoles, centers on a huge floating structure called The Cube. It appeared in the sky in the years following the events of the first game, Atomic Heart, and has become the epicenter of increasingly dangerous phenomena. In order to save humanity, we must map and decipher its secrets, which is not so easy: although geometrically almost perfect, it is constantly changing, behaving erratically, and teeming with enemies. The solution lies in the central core, where the key to humanity's survival is hidden. 1

On 12 June 2025: Mundfish also held its own expanded show, in which we saw the games they presented at the Summer Game Fest 2025. In this case, we were able to admire the trailer for The Cube once again, but we also saw a short gameplay scene from an early version. 2
