Berserker

From Doom Wiki

This article is about the Doom 3 powerup. For the Doom RPG powerup, see Berserk pack#Doom RPG.

The Berserker powerup in Doom 3 has a lot of things in common with its classic counterpart the berserk pack. However, the berserker only has an effect for a limited duration and also makes the player invulnerable in single player as well as the enhancement of melee attacks. It also enhances the damage far beyond what the classic powerup did, enabling the player to kill even the toughest non-boss monsters with a single punch.

It is also notable for blurring the player's vision and causing the player character to constantly scream while its effects are in force.
