F.E.A.R. Perseus Mandate

F.E.A.R. Perseus Mandate is the second standalone expansion pack for the first-person shooter psychological horror video game F.E.A.R. First Encounter Assault Recon. Developed by TimeGate Studios and originally published by Vivendi Games under the Sierra Entertainment label, it was released for Microsoft Windows and Xbox 360 in November 2007. The Xbox version was only available packaged with the first expansion, F.E.A.R. Extraction Point, and released as F.E.A.R. Files. On the PC, as well as a standalone release, Perseus Mandate was also bundled with the original game and Extraction Point for F.E.A.R. Platinum Collection, which was also released on Steam in 2012 and GOG.com in 2015. In 2021, F.E.A.R. Files was added to Microsoft's backward compatibility program, making the games playable on the Xbox One and Xbox Series X/S. Neither expansion is now considered canon, as the Monolith Productions-developed F.E.A.R. 2: Project Origin ignores the events of both.

The game is not a narrative sequel to Extraction Point, but rather a "sidequel" that runs parallel to the second half of the original F.E.A.R. and most of Extraction Point. The story follows a new player character who is a member of a secondary F.E.A.R. team tasked with investigating Armacham's Perseus Project. Finding themselves facing a previously unknown and highly skilled mercenary squad, the team must race to stop the mercs from acquiring potentially dangerous information pertaining to Alma Wade and Paxton Fettel.

The game received mixed reviews on both systems. On the PC, although they praised the combat mechanics, critics were unimpressed with the dated graphics and the game's similarity to the previous titles in the series. Similarly, on the Xbox 360, most critics found F.E.A.R. Files dated and too similar to the original. Critics were also unimpressed with the new player character, noting that he is virtually identical to Point Man in every way.
