Alien blaster

The Alien Blaster is a small energy weapon which appears in Fallout, Fallout 2 and Fallout 3.

Fallout and Fallout 2
A strange gun of obviously alien origin. Looks like it can support small energy cells, however.

Location
In Fallout, the Alien Blaster can be found only in the "UFO Crash" special encounter.

In Fallout 2, the Alien Blaster can only be bought from a merchant that you can meet during a random encounter north of Modoc.

In Fallout 3, the Alien Blaster is near by Powerplant 13 (up on map by way) (you can tune Allien radio SOS signal)

Fallout 3
In Fallout 3, the Alien Blaster can be obtained from the body of a dead alien lying a few feet away from his crashed spaceship. The spaceship is found west of Greener Pastures Disposal. It is not marked on the map. You'll know you're getting close when you pick up the "Recon Craft Theta" radio signal. The Alien Blaster uses unique ammo that is extremely hard to find. 120 shots can be found next to the spaceship. You can also find this rare ammo in Fort Independence, lower level, outcast weapons room. [Hard door] You can also find an Alien Blaster and a bunch of ammo under a statue near Tepid Sewers. There is also some ammo located further west in the immediate area of the LPB broadcast tower to the west of the crash site
