Heretics never rest, and the Lamb is in need of an ally. Unholy Alliance introduces a new playable character to Cult of the Lamb: the Goat! Summoned by blood and born in corruption, this wicked new ally can join the holy Lamb in local co-op. Crusade through dungeons, slay heretics, build your cult, and seek new powers together. But there’s more. As well as the addition of co-op play, the Unholy Alliance expansion also adds new tarot cards, relics, buildings, fleeces, follower traits, follower quests, and other secrets to discover!

Experience the entire Cult of the Lamb campaign in local co-op, with one player inhabiting the role of the Lamb and the other taking on the mantle of the Goat. Enjoy new 2-player twists on existing minigames like fishing and knucklebones, and choose from a selection of corrupted weapons, tarot cards, curses, and relics as you embark on co-op crusades.

Unholy Alliance adds a huge number of new follower traits, making your flock more diverse, unpredictable, and charismatic than ever. Cultists can be insomniacs, bust law-breaking friends out of prison, enter a catatonic state after the trauma of a resurrection, or become afflicted with a curse: and that’s just a tiny handful of the quirks you’ll encounter as your cult grows.
