Bio-gas canister

The bio-gas canister is a weapon in the Fallout 3 add-on Point Lookout.

Characteristics
It deploys a cloud of natural gas on the target. As with all gas leaks, it will ignite from explosives, energy weapons and conventional fire while inside the cloud. This results in a fireball on the target. The flame of the gas itself won't actually damage your enemy badly, but it will stun them, giving you an opportunity to flee should you choose to do so.

When the grenade explodes it gives out at least 5 radiation, going down to 1 radiation as well as not stopping until shot into. Enemies carrying weapons such as a flamer or heavy incinerator can be lit aflame instantly simply by throwing the canister at them, due to the flamer and heavy incinerator having a small flame at the end of the weapon which will ignite the gas.

Locations

 * 17 bio-gas canisters in total can be found over the course of the quest An Antique Land in the excavated muck holes. 7 are located in the muck holes themselves, and 10 are rewarded upon completion of the questline. They cannot be found anywhere else.
