Kernel Hearts is set to release in September 2026 for PlayStation 5, Xbox Series X/S, Nintendo Switch 2, and PC via Steam.
It is an action RPG with roguelike elements and cooperative gameplay for up to four players. Players take on the role of members of the M.A.H.O.U unit, climbing the Tower of Babylon, battling angelic creatures, and trying to overthrow God to save a world covered in ashes.
During each expedition, it is possible to combine attacks, spells, movement, and special powers, and after returning to the laboratory, players upgrade their unit using chips. The game also features a transformation into magical girl form, boss battles, and deepening relationships with allies.
