Alien worker

s are alien non-player characters in the Fallout 3 add-on Mothership Zeta.

About
Alien Workers are the working force of the Mothership. Although displayed as hostile, they never attack the player and instead always flee. Killing one results in a Karma loss. During the quest Not of This World, when you first spot them, Sally will tell you not to hurt them because they are harmless.

Appearances
s appear only in the Fallout 3 add-on Mothership Zeta.

Bugs

 * Sometimes, when the workers appear to cower in fear in front of you, they may clip into the floor.
 * 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 (PC), although a karma loss can be avoided if you have a drone under your control as it will attack and kill the workers without the player suffering any negative karma effect.
