Energy cell pack

This article is about the Doom item. For the Strife item, see Energy pack.

An energy cell pack sits above a pool of blood in Doom E3M3: Pandemonium.

An energy cell pack is a "battery" of plasma cells, shaped like a large black and gray car battery, that serves as the larger ammo container for the plasma gun and the BFG9000. It contains 5 energy cells (which have twice the usual amount of energy on the I'm Too Young To Die and Nightmare! skill levels). Each BFG shot consumes 2 whole cells, while the plasma gun empties one cell with 20 shots (1 whole cell and 40 shots in NM and ITYTD). Thus, one pack can provide 100 plasma rifle shots, or two BFG shots with 20 ammo left over.

Each shot from the plasma gun does 5-40 hit points of damage, determined using Doom's pseudorandom number generator. BFG damage calculations are more complex; a direct hit inflicts 100-800 points, after which additional energy damage is discharged, that can take the total damage into the thousands of hit points.
