Cult of the Lamb is centered around a lamb, controlled by the player, who is tasked with forming a cult in order to appease the deity “The One Who Waits”. Having saved the player character’s life at the start of the game, it instructs them to embark on roguelite-style “crusades” by venturing out into one of the game’s four regions in order to defeat various enemies (so-called “heretics”). There they can find or rescue other captured or lost animals in order to create and grow a cult following dedicated to the player. The randomly generated world contains resources to gather, perks and weapons to collect, enemies in the form of rival cultists and non-believers to fight, and other animals to rescue; these animals can be indoctrinated into the player’s cult. They have appearances that can be changed and both positive and negative traits, which can affect how they act in the cult or how they react to the player’s actions regarding the cult.
