Alien Power Cell (Fallout 3)

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

Fallout 3
A maximum of 362 alien power cells can be found, without the raider glitch.
 * 24 can be found together with the Firelance in a random encounter, which takes the form of a greenish explosion overhead. NPCs around encounter area can also pick them up.
 * 120 (10 stacks of 12 cells) can be found in and around the Alien Crash Site.
 * 96 (8 stacks of 12 cells) can be found under an overturned truck in a radioactive crater due east of Fort Bannister. When you see bombed out buildings you may want to adjust your heading a little to the north so as to come right into it. There may be some Enclave at the site and an Enclave Scientist at the truck checking it out.
 * 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).
 * It is also possibe to get alien power cells by finding a group of raiders killing one and placing the alien blaster and 1 ammo on his body, then break the other raiders' weapons, once one of them pick up the blaster kill him and look at his inventory he should appear to have one take it back and look at your alien ammo there should be more, usually around 10' note: this works best with raiders.

Broken Steel
A maximum of 425 more can be found in Broken Steel.
 * In Broken Steel more can be found inside Olney Powerworks. In the room with the automated turrets and walls of computers, just above the turrets there are two ammunition boxes each with an average of 46 (Scrounger-affected esteem).
 * A nice amount can be found in the Armory of the Mobile Enclave Crawler at Adams Air Force Base along with an Alien Blaster: from 10 to 12 are inside the Alien Blaster case in the armory (this particular stash is NOT affected by the Scrounger perk). Plus, inside the 3 medium-locked ammo crates just below the Blaster's, you will find an average of 46 cells each, pretty much like the containers in Fort Independence's storage room, assuming that you have the above mentioned perk; otherwise, you will not get more than 30-36.
 * During the Shock Value quest, as you near the core of Olney Powerworks and the Tesla Coil there are around 36 (3x12) power cells laying on the Tesla Stoves and tables in the room directly before the Tesla Coil.
 * If you destroy the Citadel during the "Who Dares Wins" quest, 72 (6 clips of 12) can be found in the armory in a room with mini nukes and tesla cannons.

Mothership Zeta
There are approximately 365 APCs on Mothership Zeta, there may be more but this is the list so far:
 * 48 (4 x 12) on the back shelf of the room where you reunite with Sally after she guides you through the Steamworks, there is also a healing archway and two containers in the same room.
 * 44 (2 x 12, 1 x 20) in the Robot Assembly area, downstairs in the first chamber, on a corner shelf near a teleporter room, near several Alien Epoxies.
 * 26 (2 x 13) in a box with a Nuka-Cola Quantum on the second floor of the Engineering Core where Sally and the other NPCs are located, it will only appear after the third core is destroyed. The box is located on a railing behind the Workbench, you will have to either jump or pull it over from the side.
 * 51 (3 x 12, 1 x 15) on the shelves next to the Atomic Pulverizer, in the Weapons Lab area.
 * 87 (6 x 12, 1 x 15) on a set of tables towards the end of the Weapons Lab area near where the Destabilizer is found; they can be found with some assorted items like a Gatling Laser, Plasma Mines, and Tesla Armor.
 * 109 (7 x 12, 1 x 25) on a set of shelves under a catwalk in the Biological Research area, where you reunite with Sally and the others.

Tips for locating

 * 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.
