For an overview of alien blaster models in the Fallout series of games, see Alien blaster.

Firelance is a weapon in Fallout 3. It is the unique variant of the alien blaster.


In addition to its 100% critical chance and high damage, the Firelance sets its target on fire upon strike, causing 2 points of damage every second for 5 seconds. Both the Pyromaniac and Xenotech Expert perks affect this weapon and it uses the rare alien power cells as ammunition.


Firelance can fire 63 shots, the equivalent of 7 reloads, from full condition, before breaking.

The Firelance can only be obtained in the "Unidentified Flying Debris" random encounter or through console commands. See Fallout 3 random encounter locations (Type A) for locations where this event may take place. The encounter occurs only once per game (character playthrough).


  • There is no guaranteed location and the ammunition scatters across the general area of the event which can make recovering it a difficult task.
  • The Firelance event produces a brief radiation field which is usually centered on the weapon itself. The weapon may not always be found within the irradiated area but will usually be very nearby.
  • The Firelance can get stuck on buildings, such as a water tower.
  • If the Firelance event took place near hostile non-player characters, they may utilize the Firelance. If the Firelance has fallen on top of a building the non-player character will take the Firelance to use, even if it couldn't normally be picked up. It will be retrievable by simply killing them and taking it off their corpse.
  • Normally, this weapon is weaker (but still very hard-hitting) than the alien blaster due to its burning effect. However, with the Pyromaniac perk, its power exceeds that of the blaster. It still wears down significantly faster, though.
  • The Firelance and the Experimental MIRV break down faster than any other weapon in the game.

Behind the scenesEdit

  • The Firelance is a reference to an identically named martian weapon appearing in the Wasteland paragraph book, in the red herring Mars plot.
  • Both the Firelance and the alien blaster resemble Commander Adams' pistol from the 1956 movie Forbidden Planet, both in design and firing. The "bullets" disperse in a very similar way when they hit solid objects, such as walls.
