Kernel Hearts Platforms: Every PC Storefront, Release Date & System Specs

Kernel Hearts is shaping up to be one of the most anticipated indie co-op action RPGs of the season, but before you rally your squad, you need to know exactly where you'll be able to play it. If you're researching Kernel Hearts platforms, the short answer is that the game is heading to Windows PC through two major storefronts: Steam and the Epic Games Store. Understanding those Kernel Hearts platforms matters because your choice can affect pre-order bonuses, achievements, refund policies, and even the system requirements you'll need to meet.

What Platforms Is Kernel Hearts Available On?

As of today, Kernel Hearts platforms are confirmed for PC only. The official Kernel Hearts on Steam page and the Kernel Hearts Epic Games Store pre-purchase page both list Windows as the sole supported platform, with a launch date of September 17, 2026. No PlayStation, Xbox, or Nintendo Switch versions appear in any official store listing, which means PC gamers get first crack at climbing the Tower of Babel.

The game is being developed by Ephemera Games and published by Whitethorn Games. On the Epic Games Store, the base game is priced at $19.99, and pre-purchase is live right now. On Steam, the game is currently available for wishlisting, and a playable demo is available on both storefronts.

Both storefronts describe the same core experience: a multiplayer co-op roguelike action RPG about four magical girls trying to dethrone God and save a world drowning in ashes. You'll climb a shifting, sentient Tower of Babel, fight angelic guardians, and customize your Unit M.A.H.O.U. OS with up to 256KB of chips between runs.

The story sets you up as part of the M.A.H.O.U Unit, tasked with eliminating the angels that protect the tower's floors and restoring hope to humanity's last survivors. Between expeditions, you'll return to the city of Babel, where you can socialize with a diverse cast of NPCs, deepen bonds through gifts, and prepare for the next run.

Steam vs. Epic Games Store: Which One Should You Pick?

When it comes to Kernel Hearts platforms, there's no wrong answer, but there are meaningful differences between the two storefronts. If you're the kind of player who lives for achievement hunting, Steam is the stronger choice. The Steam version supports Steam Achievements, Family Sharing, and online co-op, alongside single-player play.

The Epic Games Store version, on the other hand, is currently the only place where you can officially pre-purchase the game. Epic is also throwing in the Fernet Outfit in Fortnite as a gift-with-purchase, which is a nice bonus if you're a Fortnite player. Epic Rewards members earn 5% back on the purchase, and the store listing notes that the game is self-refundable.
