Armacham Riot Security Guards are a type of Armacham Technology Corporation security force that appear in the non-canon expansion, F.E.A.R. Perseus Mandate. They are not considered to be part of the official timeline.
F.E.A.R. Perseus MandateEdit
Riot Security Guards are a more heavily armored version of the ATC Security Guards, and are capable of going head to head with Replica soldiers, despite only carrying light weaponry. They have enhanced health and armor, which makes them more durable than most Replica soldiers, and only slightly less than a Replica Elite Soldier.
A handful of Riot Guards can be found in the game's earlier levels, leading regular ATC security guards or fighting against Replica soldiers. Almost all of the Riot Guards in the game appear in Interval 03 - Apprehension - The Plaza Chase, where they serve as the Sergeant's main opponents.
The Riot Guards, much like all ATC forces, are not seen after the Origin facility explosion.
The Riot Security Guard is selectable in multiplayer deathmatch.
