Files is a complete stand-alone expansion pack series for Xbox 360 featuring the all-new F.E.A.R. Perseus Mandate campaign, as well as F.E.A.R. Extraction Point. FEAR Perseus Mandate offers the ability to jump-in and experience the fright with a brand new team in an all-new experience that presents a different perspective of the events that occur at Armacham. The campaign reveals a parallel story allowing players to take the role of a different F.E.A.R. soldier and battle new enemies that the original team never saw coming.
