Gas Canister

The  is a hand-thrown poison weapon introduced in Worms 4: Mayhem. It consists of an orange, roughly-spherical orb with small canisters protruding from its surface. In most respects, it handles just like an ordinary Grenade; the fuse can be set between 1 and 5 seconds, and the player charges their shot to throw it. However, rather than exploding when its fuse is up, the Canister bursts and releases a cloud of toxic green vapors, poisoning enemy worms in the area.

Use
 CAUTION:  This weapon can poison friendly worms!
 * (X-Box) Use the White button to cycle through the Grenade Fuse settings; use the left thumbstick to turn to face the direction you want to throw, and use the right thumbstick to adjust the angle of your shot. Press and hold A to charge, and release A to throw the Canister.
