Berserk Hunter

The Berserk Hunter is the second boss in Doom 3: Resurrection of Evil. It guards the monorail leading from Erebus Labs to Phobos labs. The Berserk Hunter has a sloth-like head, and has normal humanoid legs compared to the Hell Knight's backwards-jointed goat-like legs. It is also noticeably larger than a Hell Knight, and stands a full head taller.

The second Hell Hunter, Berserk is extremely fast with powerful melee attacks. It attacks by leaping at the player, after which it will pause for a split second and open its exposed rib cage, revealing its heart. The only way to successfully fight it is to use the Helltime power of the Artifact to slow it down and shoot the heart whenever this occurs. After each leap attack, the creature will become invulnerable and charge up and throw a large fireball at the Marine. It will do this 3 times in a row before resuming its leaping melee attack. The fleshy growth pillars in the room are best used to defend against the fireballs.

Upon death, the Berserk power is attained by the Artifact. A much more powerful version of the original Doom's berserk pack item pickup or Doom 3's Berserk artifact, the Marine can punch hard enough to kill all non-boss monsters with one punch, the force sending them flying off their feet.
