Electron Charge Pack (Fallout 3)

The Electron Charge Pack is a type of Big Guns ammunition found in the game. It is used with the Gatling Laser, its unique variants (the Precision Gatling Laser and Vengeance), as well as the Tesla Cannon.

Sources of Ammunition
The Electron Charge Pack is very rare, but it can be found in a few places, most of which are entirely dependent on the type of enemies the player encounters:


 * Sentry Bot enemies that have a Gatling Laser weapon often carry many rounds.
 * Merchants occasionally stock up on the ammo type. Like 5mm Rounds, they normally have many in their inventory at one time.
 * Enclave, Brotherhood of Steel, and Outcasts occasionally carry a Gatling Laser, as well as the ammo for it.
 * With the Broken Steel add-on, Super Mutant Overlords (encountered from level 18) also carry the Gatling Laser and ammo for it.
 * Acquiring the Scrounger perk makes this ammo much more plentiful.

There are six locations that will always hold an Electron Charge Pack:
 * 1 in Evergreen Mills Foundry, on a table with a radio,
 * 1 in the Mechanist's Forge, in the room with the dead protectrons ('Sector A' as noted on the computer terminals)
 * 4 in SatCom Array NN-03d-B, the "knights" on the completed Chessboard.
 * 7 are available after completing Operation: Anchorage in the VSS Armory.
 * Around 32 can be found in the Broken Steel DLC inside Old Olney Underground just when your going up the ramp into the hospital. At the top turn around, they will be there along with a frag grenade.
 * Flak n Sharpnel's in Rivet City
 * Lucky Harith after 2nd investment
