Just one week into the game being announced with big name Hollywood stars involved in horror classics like Halloween, and F.E.A.R. 3 is already starting on details of the game's co-op mode, as well as some information on character abilities. This bit of information comes straight from the latest issue of Game Informer.
For the co-op mode, the two brothers Paxton Fettel and Point Man work together to chase down and stop their insane demon mother, Alma. You know, the usual family crisis. Point Man is played as a soldier and will have a sort of cover system available to him to hide from all the crazies, while Fettel will be a psychic who can take control of said crazies.
F.E.A.R. 3 will also tote a 'divergent co-op' that allows both players to go where they please, without actually helping one another. The developers also mention that they drew a lot of inspiration from the AI Director system in Left 4 Dead to make the enemies more frightening and unpredictable.
F.E.A.R. 3 will include all of this as well as the single player mode and competitive mode in the full release when it comes to PlayStation 3, Xbox 360, and PC sometime this fall.
