Ubisoft's Assassin's Creed 4: Black Flag and Watch Dogs will each feature downloadable content that will be exclusive to PlayStation platforms for six months. That's according to small print in the US version of yesterday's PS4 promotional video that focused on the platform's exclusives.
At the one minute fifteen second mark, small print notes that the Assassin's Creed 4 and Watch Dogs DLC is exclusive to PlayStation for six months. We already knew the content would have an exclusivity period on PlayStation, but we previously didn't know for how long.
The European version of the trailer doesn't contain the same note.
The PlayStation exclusive Assassin's Creed 4 content features an older Aveline de Grandpre, who was the protagonist of last year's Vita title Assassin's Creed: Liberation. It takes the form of an hour-long story divided into 3 missions. We don't know yet what the Watch Dogs content will be.
It seems likely that this content will eventually appear on other platforms, but at present there is no official confirmation.
