Drops on death


  • Alien workers cannot open many of the doors that the player can open, including many of the "force-field" doors.
  • Because of how they are programmed to act, it is not uncommon for alien workers to take refuge near their more hostile brethren. This makes using area of effect weapons ill-advised unless the player does not mind losing the karma.
  • Elliot Tercorien will attack them, though the other companions with you will ignore them.
  • If you want to wait/sleep on Mothership Zeta you may have to kill all nearby workers as they count as hostile enemies.


Alien workers appear only in the Fallout 3 add-on Mothership Zeta.

  • The alien workers can cause scripting issues throughout the game. Your colleagues react differently if one is near, often disrupting scripts. Thus, for example, if there are alien workers in the observation bay area when you first enter, when Sally ports through, she may well port straight out again, without opening the doors. If scripting errors occur, it may be advisable to reload to a previous save and kill all the alien workers before trying to trigger a script. This can have a significant impact on your karma, although a karma loss can be avoided if another non-player character kills them for you, such as a friendly drone or abominations.
