F.E.A.R. Perseus Mandate is the second expansion pack to F.E.A.R. The game's action and horror elements are tied to a plot filled with backstabs and double-crosses as senator, his lackey and a group of shadowy mercenaries clash in their journey to unlock the mysteries revealed in the previous F.E.A.R games. In addition to the weapons from the first two F.E.A.R games, in Perseus Mandate the player has access to a grenade launcher, a lightning gun and an advanced rifle, all of which will be necessary to dispatch a tough new cast of bad guys. Unlike the previous expansion, this title can be played stand-alone and does not require the original game.
