Fallout 3 Hints
Gas Corridor Warnings
1 of 3: Kill off all the nearby mirelurks before entering the corridor, since firing a gun in it will ignite the gas.
2 of 3: Also, watch for a tripwire that goes across the corridor just past the door on the right.
3 of 3: Be sure to deactivate or jump over the tripwire, since tripping it will drop a "grenade bouquet" in the room ahead, and the gas will be ignited around you by the grenade explosions.
