The alien power module is an Energy Weapons ammunition of alien origin found in the Fallout 3 add-on Mothership Zeta.


The alien power module looks exactly like the alien power cell in appearance.

Weapons using this ammunition


They are found commonly in "alien crates" and the inventories of almost every enemy aboard Mothership Zeta.


  • At the end of Mothership Zeta, talking to Sally every 24 hours will yield a random alien item and around 40 alien power modules. However, the game may or may not display information stating that they have been added to inventory. This means the alien power modules are unlimited, yet may take a while to accumulate in considerably large amounts.
  • It is identical in look to the alien power cell, but is much more common and is used in more weapons.
