PAX-22 Tranquilizer Rifle

The PAX-22 is a weapon in Deus Ex: Human Revolution.

Background
The PAX-22 Tranquilizer Rifle is a non-lethal, silent weapon made by Military Arms of Ostrava (MAO) located in the Czech Republic. It was intentionally developed for capture operations on wildlife and other organic targets.

Characteristics
The PAX-22 is a one-shot weapon that uses break-action loading. The darts are propelled by compressed air from an HPA (High Pressure Air) tank located under the rifle's receiver. The PAX-22 features a scope similar to the crossbow.

Range: 45 meters.

It uses hypodermic darts manufactured by Kaiga Incorporated under the name of "hypo-dyne black". These are usually sold in packs of 5 darts. They consist of a mixture of different psychoactive drugs and anaesthetics such as diazepam, phencyclidine, ketamine and morphine.

In-Game Description
The PAX-22 Tranquilizer Rifle is a long-range, single-shot nonlethal firearm that knocks individual targets unconscious. Upon firing, the PAX-22 fires tranquilizer darts that inject nonlethal sedatives into the target, and after several moments the organic enemy will be incapacitated. Headshots on vulnerable enemies will instantaneously knock out the target. Although fitted with a scope, the tranquilizer darts fired by the PAX-22 both drop and have a travel time. These factors must be considered when going for long-range takedowns.

Upgrades
The PAX-22 supports standard reload speed upgrades, along with the target-leading package, an active mod which alters the scope to provide an aiming point when active, allowing more effective targeting of moving enemies.

Trivia

 * The PAX-22 is mostly based on the Pneu-Dart (X-Caliber) Rifle, using the same reloading technique and has a lot of its design. The firing-loading mechanism may have also been inspired by the Thompson Arms Contender pistol/rifle.


 * "PAX" translates into "peace" from Latin to English. The designation of the PAX-22 is fitting given its role in the Pacifist trophy/achievement.


 * In the film, Serenity, a chemical named PAX-22 is introduced to the air supply of a terra formed planet in an attempt to calm the population.
