DOOM 3: BFG Edition

A fair distance into Doom 3 RoE you have to fight this boss before getting to the next stage so you can't miss this. This is fairly easy you just have to shoot it in the heart when it glows. When it glows just slow time with the artifact, get real close and shoot him in the heart as much as possible. I would suggest the chain gun for this. Eventually its heart will be blocked and he will start shooting fireballs, just hide behind the poles until his heart is unblocked again and repeat what you did earlier. Eventually it will die and you will get your achievement.

This will be your second boss in the resurrection of evil campaign, and actually comes a decent way into the game. He will appear in Erebus level 6, and you should warrant his appearance by noticing a square room with 4 pillars sticking out of the ground. I would advise going into this battle with the artifact fully charged and readily equipped. This is because the boss is fast and will immediately lunge at you when the fight begins. Therefore when you gain control of your marine immediately activate hell-time with the artifact.

The hunter is VERY quick and can deal some very nasty melee damage therefore you need to use the hell-time power to damage it. The first phase will consist of the hunter encircling it-self with flames and jumping around. While it is doing this you must activate hell time to slow down time and shoot at the hunters glowing red heart in its chest. I recommend the double barrelled shotgun or chain-gun to do this.

Once enough damage has been dealt, the hunter will start charging up fireballs to launch at the player. These will deal ALOT of damage and should be avoided either by strafing or hiding behind the fleshy pillars the game has given you. Eventually it will stop throwing fireballs and start phase 1 again of jumping around. Simply repeat the hell-time ability and shoot at its heart again.

You must complete this cycle about 3-4 times before the hunter will go down for good. Do be careful as the hunter can deal ALOT of damage with his fast jumping attacks and even more damage with his fire balls. There are however pre-dead human corpses within the room to charge up the artifact again, should you need to. Best of luck and remember to keep strafing or at the very least moving to dodge the demons attacks.
