Kernel Hearts in second Xbox Game Pass wave of September 2026
In brief
- Kotaku reported on September 15, 2026 that Kernel Hearts is part of the second Xbox Game Pass wave for September 2026.
Kernel Hearts is named in that coverage as one of the games in the September 2026 lineup.
Kotaku describes Kernel Hearts as a hack-and-slash MMO, while official and store context presents it as an action RPG with roguelike elements and multiplayer co-op.
What happened
Kotaku published an article on September 15, 2026 about the second wave of Xbox Game Pass games for September 2026. In that roundup, the site names Kernel Hearts alongside other titles coming to the service. The headline and the article text place the game explicitly in the context of Xbox Game Pass's September lineup.
In the same piece, Ethan Gach writes that Kernel Hearts is a hack-and-slash MMO and that the game seems to be trying to do a lot at once. That wording comes directly from Kotaku's reporting and is the site's own description of the game within the Game Pass overview.
The available source context links Kernel Hearts to Ephemera Games. On the official site and on Steam, the game is described as a mix of action RPG and roguelike elements with multiplayer co-op. That context also mentions a setting in which the player, as part of the M.A.H.O.U Unit, must climb the Tower of Babel and defeat hostile angelic creatures.
The external context also includes a video metadata reference to Ephemera Games and a trailer description that calls Kernel Hearts a hack-and-slash action RPG developed by Ephemera Games. That creates a difference in how the game is characterized between Kotaku's news coverage and the official or store presentation.

Background
Kernel Hearts is described in the supplied sources in two different ways. Kotaku uses the term hack-and-slash MMO, while the official site and Steam page describe it as an action RPG with roguelike elements and multiplayer co-op. The trailer context available through video metadata also calls the game a hack-and-slash action RPG developed by Ephemera Games. Together, these details show that the genre description in the news coverage does not fully match the official presentation.
The news angle is the September 2026 Game Pass context. Within that second wave of additions, Kernel Hearts is listed as one of the titles tied to the service that month. The source making that claim is a Kotaku article from September 15, 2026, written by Ethan Gach, and the text places Kernel Hearts in the same list as other September additions.
The official context provides more detail about the game itself. Kernel Hearts is described there as a game in which the player is part of the M.A.H.O.U Unit and must climb the Tower of Babel. The description also says the player fights hostile angelic beings while saving a world "drowning in ashes." Steam repeats the same core description, including the action RPG, roguelike, and multiplayer co-op framing.
The available sources do not provide a fully detailed release or platform list in the supplied context, but they do make clear that Kernel Hearts surfaced in Game Pass reporting in September 2026. The combination of Kotaku, the official website, Steam, and trailer context is enough to place the game in that news context, but not enough to pin down every product detail definitively.
