Ammunition box

Ammunition boxes are found in many places in the Capital Wasteland. Some are locked, and all but a notable few contain ammunition when initially found. (Some ammunition boxes in Rivet City, specifically at Flak 'N Shrapnel's, are locked but allegedly empty.) The contents of most ammunition boxes randomize on a per-game basis.

These also seem to be safe containers; they do not respawn contents and can store any object the PC can deposit within them.

PC's with an upgraded Scrounger perk will find considerately more ammo in ammunition boxes than those without.

Ammo boxes can contain: 5.56mm Round, 10mm Round, .32 Caliber Round, .44 Magnum, 5mm Round, Shotgun Shells, .308 Caliber Round, Energy Cells, Microfusion Cell, Flamer Fuel, Missile, Electron Charge Pack, Railway Spikes, Dart, and Stealth Boys.

Two ammunition boxes in Fort Independence contain Alien Power Cells. There are also 150 Alien Power Cells and an Alien Blaster in Old Olney if you have the new Broken Steel DLC installed.
