About this wiki
Kernel Hearts Wiki is an independent, unofficial fan resource for Kernel Hearts, the multiplayer co-op roguelike action RPG developed by Ephemera Games and published by Whitethorn Games. We are not affiliated with, endorsed by, or compensated by Ephemera Games, Whitethorn Games, or Valve.
How we source and credit material
Facts on this site are drawn from the Steam store listing for app 2902170, Steam news, Steam community achievements, kernelhearts.com, Whitethorn Games, Xbox Wire, and official Ephemera Games videos. Images are official store stills, achievement icons, and news art rehosted with a media id. We do not hotlink other fan wikis.
Where a number or name exists only in an achievement description or a news post, the sentence says so. This guide skips unpublished floor maps, chip costs, or extra roster entries.
Corrections
If a platform, achievement percent, or unit fact is wrong, email contact@kernelhearts.info. Kernel Hearts launched on 17 September 2026 and patch notes can move numbers; source links on each page show where a table was taken from.
