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 Ostravia (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 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.

Locations

 * At the beginning of the first mission if you request a long-range nonlethal weapon from David Sarif.
 * Grayson's shop.
 * Inside a storage room in the southwest corner of the highest level of the Kuaigan district in Hengsha, near a gate to the Youzhao district.
 * Lin Fu Ren's shop in the Hung Hua Hotel during the first visit to Hengsha.
 * Tai Yong Medical, inside a ventilation shaft above the room with the conveyor belt and electrified floor. It can be accessed from the duct near the elevator that leads to the upper city. Entrance into this duct requires either object stacking or jump enhancement. With the items far down the adjacent shaft, the easiest way to reach them is to use the Icarus landing system. Alternatively, you may be able to conserve Praxis points with the more time-consuming method of dropping and stacking at least three boxes at the bottom of the shaft so that Jensen can survive the fall (shown: ).
