Berserk (Doom Eternal)

Berserk is a power-up which occurs in Doom Eternal, taking the form of a flaming red sphere containing a skull. Like the Berserk item from the previous game, when collected the player's vision is clouded with a red haze and their current weapon is replaced with the Doom Slayer's armored fists; however, they will gain a burst of super-strength for 15 seconds that allows them to kill any demon within melee range with a single hit, allowing for unique kills that frequently result in demons being ripped apart.

Tactical analysis
The Berserk is the rarest power-up in Doom Eternal, and only occurs in two locations:
 * 1) In the ARC Complex level, under the trench in the middle of Mario's Restaurant (in both the regular and Master Level versions of this stage).
 * 2) In the Master Level version of Super Gore Nest, immediately after finding the blue gore key.

The power-up's timer stops while a demon is being killed; however, it should be saved for heavy demons as much as possible as they require more ammunition to kill, and fodder demons will keep respawning until all heavy opposition is dead.

Kills made using the berserk power-up are affected by the Blood Fueled and Seek and Destroy runes; the first rune grants increased speed following a kill, and the second allows kills to be initiated from further away.

Cheat code
The Berserk cheat code can be found in the Urdak level; when activated it grants a permanent Berserk effect for the entire level. However, it can only be used in the Hell on Earth, Exultia, Super Gore Nest, ARC Complex and Mars Core levels.

The Berserk cheat cannot be used in Part One or Part Two of The Ancient Gods, and the powerup does not appear in those expansions.

Berserk kills
Being ambient demons, tentacles, cueballs and buff totems do not have Berserk-specific kills; however, a tentacle can be destroyed with one normal punch.
