PlayStation 3 owners of Ubisoft's upcoming liberty-em-up Assassin's Creed III will get an extra hour of exclusive English-thrashing action when the game launches this October.

Details of this exclusive content are shown on Amazon's updated PlayStation 3 packshot of the game, spotted by CVG.

There's currently no specific knowledge of what the exclusive content will actually entail.

Sony confirmed that Assassin's Creed III would be getting PS3-exclusive content as part of its E3 2012 press conference.

Assassin's Creed III will be released for PlayStation 3 and Xbox 360 on October 31. A PC version will arrive later.
