The Archimedes II charge, or ARCHII charge, is ammunition for a weapon in Fallout: New Vegas.

Weapons using this ammunitionEdit


It is automatically added to the player's inventory every 24 in-game hours if you rerouted the power at HELIOS One to Archimedes II during That Lucky Old Sun and Euclid's C-Finder is in your inventory.


  • Archimedes II charges share the same model as alien power cells, the only difference being the cells are orange instead of blue.

It will only show the lasers aligning but will not fire until the time is up. If you fast travel, Archimedes may fire when you reach your destination. The same may occur when restoring a saved game.[verified]
