F.E.A.R. Perseus Mandate is a stand-alone expansion pack to the computer game F.E.A.R. First Encounter Assault Recon. The expansion was developed by TimeGate Studios, the same development team behind the first expansion, F.E.A.R. Extraction Point. Perseus Mandate is part of the Vivendi Timeline, a canon consisting of the first game and Extraction Point. The Vivendi Timeline is considered non-official by Monolith Productions, the developer of the two official sequels to the first game. Thus, Perseus Mandate does not exist in the series' official canon.
