P.E.P.S.

The PEPS is a weapon in Deus Ex: Human Revolution. It is first found in-game at the Police Precinct in Detroit.

Background
The P.E.P.S (Pulsed Energy Projection System) is a modern non-lethal weapon made by Connaught, an Asian company. This weapon is slightly larger than a pistol. It does not use bullets, but rather a form of directed energy.

Characteristics
It emits an invisible laser pulse which, upon contact with the target, ablates the surface and creates a small amount of exploding plasma. This produces a pressure wave that stuns the target and knocks them off their feet, and electromagnetic radiation that affects nerve cells causing a painful sensation. The magazine appears to be a double tank like a printer cartridge in two colors. One magazine allows one shot, and is inserted at the top of the weapon.

Upgrades
The P.E.P.S. does not support standard upgrade packages.

Tactics
The PEPS, while a non-lethal weapon, is not silent like the PAX-22 and the Stun gun. The loud, bright energy pulse it emits can usually be detected by nearby guards, and it won't knock out targets unless used at point blank range. If the weapon is fired from medium range, the blast will still stun people, knocking them off their feet and making them vulnerable for a few seconds. This can allow the player to follow up with another weapon, perform a Take down, or run away. The PEPS is best used where the player does not wish to kill the target, but at the same time does not need to keep a low profile. In non-pacifist runs, the PEPS can also be useful for clearing a room full of people in one shot.
