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 air bottle located under the rifle's receiver. The PAX-22 features a scope similar to the crossbow.

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 chemical mixture out of different psychopharmaceuticals and anaesthetics such as Diazepam, Phencyclidine (PCP), 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.

The rifle occupies a 6x2 area in your inventory, and ammo is 1x2.

The PAX-22 is useful for both scouting over long distances and knocking out individual targets at long range, but can also be fired from cover at mid ranges. Due to the fact that unconscious enemies can be revived by their allies, thus raising the alert level to alarmed, the PAX-22 is best reserved for enemies that are either alone, or can be reached quickly by the player to hide their bodies.

The tranquilizer darts fired by this weapon require several seconds to take effect. Though a disadvantage in active combat situations, this can also be exploited by the player. A player may snipe a target at long range with this weapon, then reload in the time it takes for the tranquilizers to go into effect. When another enemy comes to investigate their fallen comrade, the player may snipe that target too. This tactic can be useful for incapacitating large numbers of enemies at very long range, provided the player is unseen and fast enough to shoot down all targets before they can be revived by their allies.

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.
