Ubisoft has finally laid down the dirty details to the upcoming multiplayer beta for Assassin’s Creed Brotherhood. The beta, which is exclusive to the PlayStation 3, goes live on October 4th and is open to all gamers who have preordered the title. That means if you preordered the standard, Auditore or Codex editions of the game, you’re definitely good to go.

The beta features an 8-player online kill fest that spans over two different game modes. These game modes are Wanted and Alliance. In Wanted, assassins compete for the highest game score while evading their potential captors where as in Alliance, you are teamed up with another player and you two must go on a killing spree. I’m going to assume that Alliance is just a 2-on-2-on-2-on-2 team deathmatch style of play.

Assassin’s Creed Brotherhood releases for the PlayStation 3 on November 16th, 2010.
