Bio-Gas Canister

The  is a hand grenade which is added to Fallout 3 with the Point Lookout add-on. It deploys a cloud of natural gas (most likely methane) 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 can be found in the course of the quest An Antique Land.

Bugs

 * A large bug allows for execution of major, non-essential characters without retaliation of their faction, like Slavers. Here's how you do it:
 * 1) Successfully reverse-pickpocket Bio-Gas Canisters into the target NPC's inventory  Until their health is low.
 * 2) Ignite the immensely concentrated gas cloud, killing the target. Do not hit the target. It's advised to shoot an energy weapon through the cloud to avoid personal injury.
 * 3) Rejoice.

Of course, such NPCs aren't supposed to be dead with their appropriate faction remaining friendly to the player. Expect bugs.
