Ubisoft released a heaping helping of Assassin's Creed Revelations today, including screens, and even a new trailer. Today's announcement reiterates some earlier information, like the fact that you can play as both Ezio and Altair as you explore Constantinople, and the wide cast of characters in the game.

Ubisoft also announced that pre-orders from GameStop (in the US only) will get a Penny Arcade poster, presumably drawn by Mike "Gabe" Krahulik. Any other pre-order bonuses that might be waiting in the wings weren't mentioned.

To top it off, we got a new story trailer today, detailing Ezio's motivations for retracing his past. The trailer ends with a tease that another "full" trailer is coming on June 6, which puts it just before E3. The game is due for PC, PlayStation 3, and Xbox 360 in November.
