Bio-Gas Canister

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

Background
Not intended as weapons, these are the result of a Bysshe Company research team sent to Point Lookout to survey its rich natural gas deposits. These deposits accumulated from the mass graves of thousands of Confederate prisoners who died near Point Lookout in the later years of the American Civil War.

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 cannot be found anywhere else.
