Gas is an effect featured in Dungeon Keeper and Dungeon Keeper 2, and is caused by multiple sources. These include the Poison Gas Trap and the Fart, Gas Cloud, Poison Cloud and Gas Missile Creature Spells.
Gas works by causing constant damage-over-time for any non-immune creature caught in the noxious green cloud, including your own creatures (unless it is from a Bile Demon's Fart), so be careful!
