CellE2M1

An energy cell in a secret area in Doom E2M1: Deimos Anomaly.

An energy cell is a dark gray ammo container shaped like a box and displaying small green lights or LEDs, used to power the plasma gun and the BFG9000, holding enough energy to fire the lesser weapon 20 times (20 units of energy, or 40 on the I'm Too Young To Die and Nightmare! skill levels). Each BFG shot consumes 2 whole cells in one shot (or 1 on NM and ITYTD), while the plasma gun fires one unit at a time at the highest rate of fire for any weapon in the game.

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.
