World War III
The weapon was first used during the October 6, 2016 Terrorist Attacks. Trucks containing the weapon were detonated in several major European cities, including London and Paris. In Return to Sender, Captain Price uses a canister of the gas to threaten Waraabe. The gas is then seen, and can be interacted with, during the mission Bag and Drag, forcing Delta Force operatives Sandman, Grinch, and Frost to wear gas masks, as well as Sabre and the rest of the GIGN as they track down the Chemical bombs maker, Volk.
The weapon also appears in a much more weaponized version, during the mission Flood the Market. Mortars filled with the weapon are fired at the player. The mortars hurt when they explode, and then the chemicals continue to injure the player. After a while, the chemical cloud will dissipate.
- If the player comes across the gas, but is not wearing a gas mask, it will slowly cause more and more damage to the player in a way similar to Nova Gas grenades. However, the effects appear not to make the player cough, unlike Nova Gas. The gas is also a similar green color.
