The PlayStation 3 version of Assassin's Creed 4: Black Flag will include "60 minutes of exclusive gameplay", the game's official box art has revealed.

The box art, which was released earlier today alongside the game's official announcement, confirms previous rumours that the game would be pirate themed.

However, further details on the exclusive content - or the game itself, for that matter - have yet to be officially revealed.

Although Ubisoft has yet to announce a PlayStation 4 version of the game, if the game is cross-generational, could the exclusive content be included in Sony's next-gen version as well?

Assassin's Creed 4: Black Flag was officially announced earlier today for release on Xbox 360, PlayStation 3, PC and Wii U.
