Alien Power Cell (Fallout 3)

The Alien Power Cell is an energy weapons ammunition found in Fallout 3 of alien origin. It is used with two weapons, the Alien Blaster and the Firelance. In previous games, alien weapons simply used Small Energy Cells.

Fallout 3 Weapons Using Alien Power Cells

 * Alien Blaster
 * Firelance

Locations

 * 120 (10 magazines of 12 rounds) can be found in and around the Alien Crash Site.
 * 96 (8 magazines of 12 rounds) can be found under an overturned truck in a radioactive crater west of Jury Street Metro Station (halfway to Fort Bannister, and south of VAPL-58 Power Station).
 * 2-22 without the Scrounger perk (17 on average), or 2-122 with the perk (92 on average), can be found in two ammo boxes in Fort Independence, in the Outcast weapons room (Hard locked door) where you find the Miss Launcher. The method by which the outcome is determined (rolling for 1s at a 75% chance, 10 and/or 50 times) pretty much guarantees that the results will be on the high side (i.e., near 75% of 10 or 50). For each box, the number found is:
 * 1 guaranteed
 * Up to 10 more, as a 75% chance of getting one, sampled 10 times. This means you'll almost always get at least 5, and usually 7 or 8, with a max of 10.
 * Up to 50 more, again at 75% chance, if you have the Scrounger perk. You'll usually get around 37 or 38, and extremely rarely more than 43 or less than 32 (but 0 is theoretically possible). For more info, see Talk.
 * 24 can be found falling near you together with the Firelance in a random encounter.
 * At Fort Independence, Protector Casdin has 12 that you can pickpocket (or kill him). Sometimes he is killed by an Enclave attack.



More info on the ones in Fort Independence: If you go to Fort Independence, and go in the actual building, go to Fort Independence Lower Level. There should be a tipped over Nuka Machine on the right side of the door. Once you go through that door, you will go down some stairs and come across a door with a terminal on the right. But there are enemies on the other side. And I'm not sure if it was Fawkes or the enemies on the other side, but someone opened the door and you can quickly go through it. If that doesn't happen, just make sure you have a hacking skill of 75+. Or just find the G.E.C.K. and team up with Fawkes. If you didn't, just find him/her at the Underworld in the Museum of History. Anyway, after you hack and get passed that door, go all of the way downstairs and go through another door. This will bring you to a hallway where you can take a Left and go upstairs or continue forward to downstairs. Either really doesn't matter, but it's better to go upstairs to kill all of the enemies. Once you enter upstairs and kill everyone, look down and you can see a medical area and a computer area. You can jump down and go to the computer area. Once you get down there, you can see a locked door on the south end of the room. In there is an armory with some ammo and a Minigun. On the table on the left there are two ammo crates. In those crates, there are the Alien Power Cells.

Finding Them

 * Alien Power Cells glow in the dark. This can be useful for finding them, since they are small, but they may be scattered randomly, making them hard to spot. Even small dips in the ground or tufts of grass can hide them.
 * Another way to find them is to order Dogmeat to search for ammo when the cells are nearby.
