An interesting couple of pictures emerged from E3, showing a group of four assassins printed on a giant banner used by Ubisoft to advertise the game just outside the expo's venue.

This seems to point in the same direction as a rumor emerged a while ago, indicating that a four player co-op campaign would be showcased during a demo at this Electronic Entertainment Expo.

Incidentally, the picture used for the banner also seems to come from one of the game's cinematics (the style matches), that we might get to see in the next few days.

The implementation of a co-op campaign in the game would not be too much of a surprise, as the title "Unity" definitely seems to indicate something like that, even if we'll have to wait for Monday to get an official confirmation.

Yet, if I was a betting man, I'd definitely put my money on "yes."
