Today, Ubisoft returned with preorder information on Assassin's Creed: Revelations, which is due for release on the Xbox 360, PlayStation 3, and PC on November 15. Those who purchase Revelations in advance at GameStop for the Xbox 360 or PS3 will automatically receive a free upgrade for the game's Signature Edition, granting them a bevy of in-game and bonus content

Specifically, the Signature Edition includes an extra single-player gameplay mission, as well as an exclusive multiplayer character and weapon capacity upgrades. Assassin's Creed: Revelations' special edition also features multimedia perks, coming as it does with an animated short film and an original soundtrack.

For those who would rather buy their games in advance at Best Buy, Assassin's Creed: Revelations will include an exclusive multiplayer character.

Ubisoft also announced today that it has released a range of new Xbox 360 Avatar items based on Assassin's Creed: Revelations. Earlier this week, the publisher released an Xbox Avatar collection celebrating the company's 25th anniversary. The limited-run collection expires on June 21.
