Ubisoft announced today that the Animus Project Update 1.0 downloadable content for Assassin’s Creed Brotherhood for the Xbox 360 and PlayStation 3 will be available for download on December 14th, 2010. The DLC will be made available for free.

The Animus Project Update 1.0 will include a brand-new game mode and brand new map for Assassin’s Creed Brotherhood Multiplayer. The game mode, Advanced Alliance, will make the original Alliance Mode with target identification and engagement more difficult than in original Alliance Mode, thus providing a more challenging experience for players. With three teams of two players each, Advanced Alliance is a tougher test for players and rewards teams that use stealth techniques to hunt their targets.

Located on a rocky tidal island of Normandy in France, the new map, Mont Saint-Michel, offers breathtaking scenery sure to enchant all. Its particular topography of narrow streets, high-perched bell tower and multi-leveled architecture is perfect for hunters and predators alike to surge from out of nowhere to execute their prey. To survive, recruits will need to use free-running and narrow roads to their advantage.

“We are very thrilled to be able to offer the first Multiplayer DLC for Assassin’s Creed Brotherhood for absolutely free,” said Sebastien Puel, executive producer, Ubisoft Montreal. “We wanted to say thank you to our fans for making Brotherhood such a huge success its opening week. We are very proud of the unique and innovative Multiplayer mode it offers, and hope the fans enjoy the new content.”
