Developer EPHEMERA and Whitethorn Games have announced that their action-RPG roguelike, Kernel Hearts, will be released for PlayStation 5, Xbox Series X|S, Switch 2, and PC via Steam in September 2026.
A new demo will also join Steam Next Fest on June 15, 2026.
Kernel Hearts follows a M.A.H.O.U. unit, a team of magical android soldiers tasked with climbing the Tower of Babel and destroying a god.
Beyond roguelike runs, defeated players can return to the lab to customize their loadout using up to 256KB of skill chips. These permanent upgrades enhance the distinction between playable characters and ensure that future runs are more successful. Combat rewards timing and precision, with high-speed spellcasting, dashes, and combos.
Moreover, a magical transformation system allows players to clear out cursed enemies that grow stronger the longer they remain on each floor. Multiplayer co-op is also available.
