Sierra announced F.E.A.R. Perseus Mandate, an all-new stand-alone expansion pack for PC and F.E.A.R. Files, the complete stand-alone expansion pack series for Xbox 360. Both products are scheduled to ship this fall. "F.E.A.R. Perseus Mandate offers both seasoned gamers and those who have never played the original F.E.A.R. 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."
