Energy cell pack
From DoomWiki.org
An energy cell pack is a "battery" of energy cells that serves as the larger ammo used to power the plasma gun and the BFG9000 in Doom and Doom II, and additionally also the Unmaker in Doom 64. In the original games it is somewhat shaped like a large black and gray car battery with three yellow lights, whereas in Doom 64 it is green-brown in color and has a similar pattern of three green lights as the standard cell. It contains 100 units of energy (or 200 on the I'm Too Young To Die and Nightmare! skill levels). The plasma gun uses one unit per projectile, while each BFG shot consumes 40 units. Thus, one pack can provide 100 plasma rifle shots, or two BFG shots with 20 ammo left over. The Unmaker on the other hand has a different ammo consumption depending on how many Demon Keys the player has collected, ranging from one at zero keys to three at full keys.
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 and shortly after additional damage is added with 40 beams from the player in a wide arch. This can take the total damage into the thousands of hit points if all the beams hit a valid target. Therefore, depending on its usage, the BFG can be a much more efficient use of energy cell packs than the plasma gun is. Each attack from the Unmaker (visually a laser but in practice a hitscan attack) deals between 10 and 80 points of damage, and its damage output when upgraded generally outclasses all other weapons in the game.
