Bio-Gas Canister

The bio-gas canister is a hand grenade which is added to Fallout 3 with the Point Lookout add-on.

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.

Locations
17 bio-gas canisters in total can be found in 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 can't be found anywhere else.
