Devolver Digital kicked off Volvy’s 15th Birthday Party by showing off developer Massive Monster’s next major update for the popular base-building action roguelikeCult of the Lamb. Titled Unholy Alliance, the update is set to release on Jun 20, 2025 and will add local co-op toCult of the Lamb.
Players will have the ability to play as the Lamb or the Goat when the free update releases, joining forces to tackle new dungeons, slay heretics, build their cult, and more.

I haven’t playedCult of the Lambas much as I would like to, but co-op seems like a great fit for its gameplay loop. Hopefully eventually it expands to online co-op as well, for those of us that don’t have local friends to play with.
Cult of the Lamb: Unholy Allianceis coming to PlayStation 4, PlayStation 5, Xbox, Nintendo Switch, and PC on July 16, 2025.
