Assassin's Creed: Revelations pre-orders for Xbox 360 and PS3 at GameStop -- who, by the way, notes the game will arrive November 15 -- will automatically be upgraded to the "Assassin's Creed Revelations Signature Edition," Ubisoft announced this morning. The Signature Edition will grab pre-order investors a bonus singleplayer mission, an exclusive multiplayer character, weapons capacity upgrades, an animated short film and an Assassin's Creed: Revelations original game score soundtrack

Some leftovers from all that GameStop goodness accidentally rolled over to Best Buy, which will give you an "exclusive multiplayer character" with your pre-order. They'll also toss in a look of shame for free.

Oh yeah, Ubisoft also launched an AC:R Avatar fashion collection on the Xbox Live Marketplace if you're interested.
