Sometimes it's good to be an Xbox Live Gold subscriber.

Larry "Major Nelson" Hyrb announced that Assassin's Creed II joined the Games With Gold program, meaning gamers with that level of membership can download it free-of-charge. Originally released in 2009, the game introduced players to Ezio Auditore di Firenze, who stuck around for two sequels, Brotherhood and Revelations.
