Far Cry 4: Complete Edition is on its way to the PlayStation 4 and PC. This means that the last generation platforms and the Xbox One will not be getting it. The game will include the season pass, along with all the the DLC content.
As of right now, the release date is the 19th of June for the UK. There is no word of the game releasing anywhere else at this time. Hopefully it will see a release here in the US, which I am sure it will.by
