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. Its attack method encompasses two phases. First, it invokes its Berserk ability (denoted by a rise of flames around it) before making a very fast leaping attack at the player. It is while it is Berserk that it exposes its heart and becomes vulnerable. You must use the Helltime power of the Artifact to slow it down once it becomes Berserk and attack its heart (one Helltime session should be sufficient to unload a full magazine of Chaingun shots at it). If you attack it enough just as it finishes its Berserk invocation, you can preempt the leaping attack, but even if the leaping attack isn't stopped, Helltime is probably the only way to actually dodge the attack, and you'll still have time to attack once it finishes its leap.

Once its Berserk attack finishes, the creature will become invulnerable again and go into its second phase. It will leap back, keeping its distance from you, and charge up and throw a large fireball at the Marine. It will do this 3 times in a row before returning to its Berserk attack phase. The fleshy growth pillars in the room are best used to defend against the fireballs. The fireballs can also be dodged by straferunning.

Kill the Hunter and the Artifact will absorb the Hunter's Berserk power. 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.
