Ubisoft have released a trailer for the coop portion of Far Cry 3. This is an entirely different campaign where you and three of your friends get to have your own adventure on the island. This is the first attempt at coop for a Far Cry game but it looks pretty solid with some standard elements (reviving teammates) and some perhaps new elements (each player selecting their own load out at the start).

Far Cry is set to release on PC, PS3, and X-Box 360 on December 4, 2012.
