The second expansion pack to F.E.A.R. finds the player leading an alternative F.E.A.R team tasked with investigating the Perseus project at Armacham facilities. For this mission the player is partnered with Captain David Raynes and Lt. Steven Chen, who do their best to assist the player throughout the campaign.
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.
Various blood and gore effects were removed in the German version.
Subway
In one of the levels, The Sergeant goes through a subway to reach the surface, where he appears at an airplane crash site. This is the same spot that appeared in the first expansion, Extraction Point, when The Pointman (protagonist of the first game and the first expansion) was entering the subway. It should also be noted that The Sergeant was there before The Pointman, as the Replicas are still deactivated. In the same level, while The Sergeant is still in the subway/tunnels, the crash can be heard, and a subsequent quake noticed. This is the only place that is visited multiple times throughout the series.
The Sergeant
Although players aren't supposed to see the face of the protagonist, the Sergeant actually has a fully made face model. It can be viewed when accessing the game files.
VES Advanced Rifle
The VES Advanced Rifle (a new weapon found in F.E.A.R.: Perseus Mandate) is a fictional gun, but is based on the XM8.
