GameStop have announced that they are giving away a Harlequin character for everyone who pre-orders Assassins Creed: Brotherhood from them.
Harlequin is a clown like character, no details or anything about his weapons or tactics, but what is revealed is that “Behind the gaudy costume and twisted smile lies the soul of a merciless assassin. You call yourself the Harlequin. Your victims will call you a walking nightmare.”
GameStop is one of many retail stores that will give different bonus characters once you pre-order Brotherhood, no other retail store has described their bonus yet.
