South Park: The Stick of Truth does not use Ubisoft's digital platform Uplay, developer Obsidian has confirmed.
On Twitter Obsidian said Uplay had not been integrated into the role-playing comedy at all, despite the game being published by Ubisoft.
Rather, it's a Steam game with all that entails, including Steam achievements.
