Yes, the story behind Assassin’s Creed is interesting and its a ton of fun to run around “real” ancient cities with crazy parkour. However, Brotherhood introduced multiplayer assassinations and the upcoming Assassin’s Creed Revelations continues with more multiplayer. The new multiplayer adds characters, locations and Abstergo Templar ranks. As you level up in the multiplayer you get higher Abstergo rankings which gives you more information on the company.
Assassin’s Creed Revelations is set to be released on November 15th, 2011 for PC, Playstation 3, and Xbox 360.
