Replica Snipers only appear in a single section towards the end of F.E.A.R.. The Point Man will engage in a firefight against eleven of them while crossing the rooftops of an abandoned tenement area. The snipers are equipped with Type-7 Particle Weapons, and will fire at the Point Man from the rooftops and windows of the nearby apartment buildings. Notably, Snipers wear a similar uniform to Replica Fatigues Soldiers, however, Snipers do not wear red night vision goggles. Instead, their faces are covered by a white hockey-style mask (all Replica soldiers wear this mask, but most cover it with a helmet or headgear).
Replica Snipers make a return in F.E.A.R. 2: Project Origin, and are more common than they were in F.E.A.R. They only come in a few levels and carry the Raab KM50 Sniper Rifle. They do not seem to wear armor, which means they have little health and will use the Seegert ACM46 Pistol if Michael Becket gets close to them, though this often is not an option. Their red night vision goggles might be a reference to the prequel's Replica Fatigues Soldiers. Keira Stokes is pinned down by fire from a team of these soldiers, and Becket is ordered to assist her in taking down all of them. Several are encountered later on, usually running into a prepared position before opening fire.
Snipers are highly dangerous foes, even at lower difficulties where they are capable of shredding full armor with a single shot and even then, would leave the player badly wounded. At hard difficulty, they are capable of inflicting instant death to the player with a single shot. It is for this reason that cover and timing are extremely vital when trying to outwit a positioned sniper.
They are armed with the RAAB KM50 Sniper Rifle. When they use it, it has a visible red laser pointer which warns of when they are aware of Becket's position, and allows a convenient method of locating them by tracing the beam back to its source, although in bright environments with plenty of spots for snipers to pop up from, it may be a little hard to see the laser until it is too late.
Slow-Mo and the RAAB KM50 Sniper Rifle is a very useful combination when facing the Replica Snipers at long range, however, the Patten PK470 Assault Rifle can be used because of its medium-high accuracy. At close range, anything can be used to neutralize them quickly.
They are again encountered in Reborn. Most of the time, they are mixed in with other Replicas, making the encounter the third time around slightly harder than before. It is not uncommon for Foxtrot 813 to fight other Replicas while being sniped at by them in Reborn.
The Replica Snipers do not appear in F.E.A.R. 3. Most of them are replaced by Armcham Mercenaries. However, wearing their armor for even more protection than replicas to hunt down Point Man and Paxton Fettel in most of the game.
The Replica Sniper can be selected as a playable character model in the Replica faction in F.E.A.R 2's multiplayer. Because they have no armor, they have no protection, but they can carry large amounts of items.
