Metal Blaster

The Metal Blaster is a unique AER9 Laser Rifle you get in The Pitt by bringing Everett 50 Steel Ingots in The Pitt Fallout 3 DLC.

It does appear to be more powerful than a normal laser rifle and the unique Wazer Wifle. It lacks the precision of a standard laser rifle, making it much less effective for long-range attacks, but close sneak attack critical hits outside of V.A.T.S. are exceptionally devastating. It fires multiple lasers (nine) at a time while only using one unit of ammunition, a property also used by Protectron's Gaze. The Metal Blaster is one of two guns in the game (along with Lincoln's Repeater) whose skin differs from the skin of its non-unique variant. The Metal Blaster has a yellow stripe along the top that is not present on the standard Laser Rifle or the unique Wazer Wifle.

History
Everett explains that it was created by a man from The Pitt using parts he found lying around the The Mill. Everett obtained it by looting it off his corpse.
