Gas Grenades, also called Riot Captor Spray (CS) is a weapon in Deus Ex: Human Revolution. Tear gas is the name for a mix of both a substance that dissolves well and evaporates easily (for spraying over distances) and 2-chlorobenzalmalononitrile, an irritant that can incapacitate someone without outright killing them, unlike traditional weapons. When an organic target is caught in a cloud of riot CS, they will be knocked unconscious.
The R-Series CS Gas Discharger is a standard tactical anti-personnel gas grenade, capable of discharging CS Gas (Also known as tear gas) over a defined radius. A hand-thrown device, the grenade has no effect against inorganic targets or targets equipped with sealed environment masks or rebreather Augmentations; however, against unprotected organic targets, the discharge cloud causes temporary loss of vision and a nausea reaction.
The Gas Grenade can be a very useful tool for players focused on non-lethal combat, as it has the largest blast of all the explosive weapons, as well as having its effect (the gas cloud) linger for a fairly long time. The gas can stun or disable most enemies as soon as it goes off. Tossed in the right position, players can even avoid triggering a "hostile" reaction from their victims, making it a great weapon for stealth focused players as well.
Upgrades: The gas grenade is not upgradeable, but it can be turned into a very effective "gas mine" when combined with the Mark 87 Tactical Munition Mine Template.
Manufacturer: Military Arms of Ostrava.
- Similar to when hit by an EMP Grenade, Jensen will die if he is low on health instead of being knocked out. This is likely due to gameplay reasons.
