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, making recovering it a difficult task.
  • The Firelance encounter produces a brief radiation field which is usually centered on the weapon itself.
  • The weapon can get stuck on unreachable buildings, such as a water tower, or be picked up by NPCs, who happen to be in the encounter zone.
    • Hostile non-player characters may be able to pick up the weapon from unreachable buildings, in which case it can be retrieved by killing and looting them.
  • The Firelance and the experimental MIRV break down faster than any other weapon in the game.
  • Entering the console command getStageDone 00031E39 8 will return "1", if the encounter already took place in the world, or "0" if it can still occur.

Behind the scenes

  • The Firelance is a reference to an identically named Martian weapon appearing in the Wasteland paragraph book, in the red herring Mars plot.
