Berserk



The berserk pack is a powerup that looks like a black medikit. Picking one up boosts the player's health to 100% (unless it was already 100% or more) and temporarily fills his vision with a red haze.

The berserk pack increases the strength of the player's punch attack tenfold until the level ends (not only until the red haze disappears), making it powerful enough to smash humanoids to a pulp, or even kill a demon with a single blow. When a berserk pack is collected, the player's current weapon will switch to the fist.

The berserk pack can also be obtained with the cheat code idbeholds.

In vanilla Doom, a player who has the chainsaw cannot use his fists unless he has also obtained a berserk pack.

Berserk packs are included in the items percentage displayed at the end of each level.

A version of the berserk pack is also found in the first Doom novel, as a powerful intramuscular stimulant injection that Flynn Taggart uses which temporarily raises his strength to the point of killing monsters wth his bare hands, though the stimulant nearly kills him in the process due to the strain on his heart.

Doom RPG
The Berserk powerup appears in the Doom RPG but is somewhat different to the original one. The Doom RPG Berserk powerup increases the damage to all weapons by 3 instead of the fist by 10 and looks like a red soulsphere. It also doesn't heal the player. The Berserk powerup lasts 30 turns.
