With the BFG edition of Doom 3 out, we thought it might be a good idea to compile a small Doom 3 BFG Boss and Hunters Strategy guide for the game as well as those of the expansion. Following guide has precise boss battle tactics you can use to defeat the most badass of enemies in Doom 3: BFG.
Doom 3 BFG Boss and Hunters Strategy
Vagary is a female spider that can use telekinesis; she’s actually just a regular enemy later in the game – this is just considered a boss fight as it’s the first time you meet one of these.
Just keep dodging her telekinesis attacks and let her have it with whatever you have ammo for. The Chaingun works very well for this boss.
You must fight the Guardian in Hell in order to gain the soul cube weapon. A sort of ‘exploit’ way to kill him is to enter the portal with the BFG equipped and let the cut-scene finish. Firing off a fully charged BFG shot at his blue energy sphere right then should kill him.
The trouble fighting him is that he will be surrounded by a lot of Seekers ( demons with searchlight) and hence you gotta kill them first before you can get your hands onto the Guardian Boss.
If, for whatever reason he doesn’t die, continue the fight while utilizing the pillars and corners as a cover. Shoot down the aerial minions first. Once you kill these, aim for the huge energy sphere above the boss, and he should go down before long.
Equipped with a rocket launcher from the start, this boss is a really giant demon – actually a mutated Sergeant Kelly
The battlefield is a circular ring shaped area surrounded by Lava, so make sure you stay inside the ring and don’t step out of it. It gets a little troubling too because in this fight you have to keep moving.
As the fight begins, the Imps will start spawning into the ring from its center, but it is a good thing for you gotta use them to recharge your Soulcube. Yes! Soulcube is the only weapon that can kill this Giant Boss and hence you must recharge it.
If you get surrounded by the Imps, it is at this point when the game gets really troubling. The better method to deal with such circumstance is not to use Rocket launcher, shotgun or machine guns as either they are too slow or they do not cause much damage. So here you gotta use the Chain or Plasma gun for them.
The easiest way to kill him is to make sure your Soul Cube is charged when you enter the room, then right when the boss says the word “welcome,” launch the Soul Cube as well as FIVE rockets, and he should be defeated in short order.
Cyberdemon is the final boss of the game and you will face him in the CPU core.
The battlefield is a huge room type of CPU core area, consisting of 4 pillars which can be shocking sometimes. So you gotta stay away of the pillar as they will deal a lot of damage.
Besides, there are quite a lot of items lying around which serve as great aid while fighting. There is a medical kit and two cells behind the pillars and also 2 chambers. The left chamber consists of some armor and the right one consists of the medical kits.
However, you gotta be vigilant while trying to access the chambers are their doors open slowly and hence you must try for them when the battle isn’t much heated.
Do not be intimidated as he is much easier to beat than you might think, even on Nightmare difficulty. Simply maintain your distance from him as much possible and keep dodging his missiles.
Use smaller enemies to charge the Soul Cube, and then launch it at him a total of FOUR times. Four fully charged Soul Cubes will kill the Cyberdemon.
Another method of killing this Boss is to equip your BFG rocket and shoot 5 rockets at the central part of the demon as soon as the garage door opens. One of your 5 shots will demolish his initial BFG shot.
Once you do this, switch to the chainsaw and cut him until he dies. He won’t be getting up while you are chain-sawing him so it won’t be much trouble.
The first boss of the expansion, and can only be defeated by grabbing the blue-ish green fireballs that are launched at you with the Grabber and throwing them back at him.
Be careful while aiming your throws, as he can use very high bursts of speed to seemingly teleport. Five direct hits from the fireballs will kill this boss.
This boss is more aggressive than the previous boss and has two attacks. One is a leap like melee attack; the other is once again launching fireballs. When the battle starts, use the Helltime power of the artifact immediately and proceed to fire the Super Shotgun into his heart.
He can only be harmed while he is in his ‘berserk’ mode, which is denoted by a rise of flames around it. In this state, his chest is open and his heart is exposed and glowing.
The third and final hunter, this guy is one of the hardest boss fights in Doom 3. He is powered by three coils in the room that grant him invulnerability and the only way to damage him is to destroy one of the coils, as this will result in him being weakened for a short amount of time.
Activate the Artifact in these critical moments and unload with whatever you have. Eventually, the coils will re-activate, and you will have to destroy another to damage him, until all the coils are gone and his invulnerability goes away.
As the final boss of the RoE expansion, the best way to tackle this boss is to use the Bloodstone and then unload rockets into him while he is flying. Using the Grabber on the Forgotten Ones that fly out to you would be a good idea.
Dodge his attacks and when he lands, pump him full of BFG rounds, and he should go down fairly easily.
