The alien blaster is a weapon in Fallout 3.


The alien blaster is one of the most powerful weapons in the game due to a critical hit being guaranteed. This weapon will be able to take down most foes with a single shot to the head.

This weapon also has the effect of disintegrating any enemy killed with a critical hit, identical to a laser weapon (with the exception that the disintegration effect is colored blue instead of red).


The alien blaster can fire a total of around 125 shots, equivalent to 13 reloads, from full condition before breaking but will not jam until approximately 120 shots.

  • Dogmeat can be used to help recover the blaster and scattered ammo from the crash site without triggering the Mothership Zeta quest line.
  • The blue neon glow turns off when the player character enters sneak mode.
  • On Mothership Zeta, none of the aliens use this weapon besides the captain (which is a unique version).
  • In an early piece of concept art (see below), the weapon was portrayed as a small alien ship, with an added grip to be used as a handgun.
  • The alien blaster can be given to Protector Casdin for the usual payment options.
  • With Mothership Zeta installed, the Lone Wanderer will be abducted before being able to pick up the alien blaster from the crash site, though it can be picked up after they return.
  • The spent alien power cell will appear dimmer when reloading, as if drained of power. The replacement that the Lone Wanderer reloads the blaster with will appear with the same blue glow as normal.
