Burnmaster (Fallout 3)

The Burnmaster is a special Flamer in Fallout 3.

Location
This weapon can be found in Franklin Metro Utility, a tunnel system beneath Falls Church/Mason Dst Metro.

When you managed to find Franklin Metro Utility in Falls Church/Mason Dst Metro (it's all the way in the back, down the tracks past the mezzanine), follow that until you get to where the tunnel goes down into the water. Go into the water and then make a left through a broken passage in the tunnel. Swim to the right until you find a ramp that goes up. Continue down a hallway filled with radioactive barrels. The player character may want to be sure that he has brought along a bottle of Rad-X, some Rad-Away packets, or a Radiation Suit, as the area has moderately high levels of radiation, and there are 2-3 Glowing Ones. At the end are 4 ammo boxes filled with flamer ammo and the Burnmaster.
