This add-on adds a grenade which, on detonation, releases a toxic gas cloud which disorientates and damages anyone unfortunate enough to stand in it. Good for crowd control/area denial. The add-on also comes with a Gas Mask, which is a passive item allowing you to walk you through the gas cloud. Features
TTT compatible! You can make it so that only Traitors/Detectives can get them, OR make them spawn around the map for everyone's use.
Gas Mask passive item makes you immune to the gas
Players standing in the gas cough, and have their vision distorted
Easy installation; plop into the addons folder, restart the server and toss at player.
Configuration is done in mustardgas_settings.lua - everything is commented
It is generally suitable for any gamemode (TTT, DarkRP...).
