A massive poster for Assassin's Creed Unity covering one outside wall of the Los Angeles Convention Center--the site of next week's E3--shows what appears to be four different assassins. We also see the tall tower from the game's teaser trailer.

What could it mean? A past report suggested Assassin's Creed Unity would feature four-player co-op. In addition, a source previously told The Escapist that Assassin's Creed Unity would have a co-op mode and that it would be revealed at E3.

Assassin's Creed Unity launches this holiday season for Xbox One, PlayStation 4, and PC.

In addition to Assassin's Creed Unity, Ubisoft is rumored to be working on another Assassin's Creed game, subtitled Comet, for Xbox 360 and PlayStation 3. This game will reportedly let you play as a Templar.

Ubisoft's E3 press conference takes place tomorrow, June 9, at 3 p.m. GameSpot will carry a live stream event, as well as instant analysis video features immediately following the event.
