South Park: The Stick of Truth is a role-playing game set in the town of South Park, developed in collaboration with series creators Trey Parker and Matt Stone. Players control a new kid who joins a city-wide live-action role-playing game among the local children, which escalates into a conflict with larger stakes. Combat uses a turn-based system with timed button inputs, and the game features exploration, side quests, and the humor of the animated series.
