X-Men Origins: Wolverine is a 2009 action-adventure game based on the film X-Men Origins: Wolverine. The game release coincided with the release of the film on May 1, 2009, for the PlayStation 3, Xbox 360, Windows, Wii, PlayStation 2, Nintendo DS and PlayStation Portable. A version of the game was also released for mobile phones. The game was developed primarily by Raven Software through the use of Unreal Engine 3. Its ESRB rating has varied widely across platforms, with the non-Nintendo console and PC versions being entitled the Uncaged Edition and receiving a Mature 17+ rating to provide players an opportunity to experience the uncensored graphic violence of the natural use of Wolverine's abilities, the Nintendo DS version receiving an Everyone 10+ rating due to its violence being tamed by reduced resolution and graphics, and the Wii, PlayStation 2 and PlayStation Portable versions receiving a Teen rating by featuring standard superhero violence consistent with what was seen in the PG-13 rated film.
