September 1, 2006 - Ubisoft sent us word that Assassin's Creed, the next-gen title that wowed everyone and their mother at this year's E3, is indeed coming to Xbox 360. The latest news confirms what has been rumored for so long and comes hot on the heels of news earlier this week that the game would be coming to the PC. Assassin's Creed on Xbox 360 will be released to coincide with the Playstation 3 version in the first quarter of 2007.
