Behemoth (mutant)



A Super Mutant Behemoth is a giant, 30-foot tall super mutant living in the ruins of Washington, DC. There are five in total, and they do not respawn after you kill them. On the Xbox 360 and Windows versions of the game, there is an achievement entitled "The Bigger They Are..." obtained by destroying all five.

Locations

 * The Behemoth right outside the entrance to the GNR Building is the easiest to find and is actually impossible to miss if you attempt Galaxy News Radio (quest). You will have ten Brotherhood of Steel members to back you up, though they are not invincible and most will likely be killed quickly. One of the Brotherhood members is in possession of a Fat Man weapon and will die quickly, before having a chance to use it.  If you have trouble defeating this behemoth it’s possible just to run to door of the GNR building. There is a back exit to this building so you will not have to face him on the way out. Also when you quick travel back to this location you will be placed behind the sandbags pretty much out of harms way near the door.

Note: On PC version Behemoth might bug out of his cage if he spots you or Dogmeat; as Dogmeat tends to attract enemy attention from a great distance, he is most likely to agitate the Behemoth before you do.
 * In Evergreen Mills, the Raider-controlled train yard, a behemoth is trapped by an electric fence and can be killed by shooting through the fence without disabling the fence. If you destroy the generator at a distance, the behemoth will attack the raiders.


 * A Behemoth can be found in the Capitol Building fighting Talon Company mercenaries at the west entrance.


 * A Behemoth is to the west of the Jury Street Metro Station, which is located due west of Vault 101. Keep going west from the Vault until you find a bunch of wrecked train cars, among which there should be one train car containing a shopping cart with a teddy bear in it. Simply take the teddy bear out and hide near by. The behemoth will appear VERY quickly.


 * The last is located near the Takoma Industrial Factory to the east of the Galaxy News Radio building at the end of the map. The Behemoth himself is located north of the factory, standing amidst some wrecked cars. There is a truck near a water tower a few feet away. Over it you can see a dead mercenary and a switch that activates some artillery that makes the fight a lot easier.

Appearances
The Behemoth appears only in Fallout 3. A robot also named Behemoth can be found in Fallout Tactics.

Physical Appearance and Equipment
Behemoths are, as mentioned, roughly 30 foot tall Super Mutants. They have short, stubby necks and extremely large build. Behemoths usually carry fire hydrants and have several shopping carts on their back. With great caution, one may also notice a necklace of skulls around their neck. They use car doors as shields.

Strategies

 * The quickest way of giving this huge ugly a permanent dirt nap is a mini-nuke to the head. Lure it into an area where you have a clear shot and then put the big sucker down. A well-repaired Fat Man does upwards of 1400 damage per shot, not to mention the knockdown potential. One mini-nuke usually leaves a behemoth with 10% of its original hit points, so while it's staggering from the impact, simply switch to the Minigun, pump 50 rounds into the big ugly, and call it a day. (Note: I managed to kill the behemoth outside GNR using this method in roughly five seconds, resulting in zero BOS casualties (other than Initiate Reddin, whose death is scripted))


 * Because of his size, he can't chase you through a hallway or low piece of rubble that you can get under. Using this, you can take your time and have a wonderful day of target practice. Just don't get too close, as his melee attack is a near one hit kill on most occasions.


 * Behemoths have difficulty getting around any kind of obstruction. Put a sufficiently tall rock between you and the behemoth and keep it there.  The Behemoth will slowly sidestep around it while you empty magazines into his head.


 * They never travel alone. One is usually supported by normal super mutants. Give the guards priority, but keep moving: if the Behemoth does hit you, then you will have more than just some nasty bruises.


 * Land mines can be set in a path, on which you can lure the Behemoth to you through the landmines.


 * If Dogmeat is still traveling with you, order him to stay in a safe place; as Dogmeat's only attacks are close range melee, he can be damaged quickly by the Behemoth, though you can deal with this somewhat by talking to him and using the "Hold still" dialogue option to use a Stimpak, which is available even during combat.


 * For the Behemoth at Evergreen Mills, if you are planning on killing the raiders you can hide up on the cliffs and snipe the sparking generator. Doing so will open the doors and let loose the behemoth and you can enjoy the ensuing carnage.  Alternatively, you can usually pick the Behemoth off slowly with a ranged weapon through the mesh gate while the generator is still active. For a clear view of his head and a faster way to kill him without destroying the generator, you can climb up on a train car near the cage and shoot at him from there.  However, it is possible that the Behemoth here may escape his cage during the shootout with the Raiders, forcing you to deal with him in the tight confines of the camp.


 * Never stay still as Behemoths are highly effective close combatants and will do significant damage if you can't maintain a distance from them. Moving backwards while firing a heavy weapon is particularly effective.


 * The Victory Rifle is also efficient. You can knock him down by using this modified sniper rifle.


 * For more advanced characters, a surefire method involves the dart thrower and the flamer. A single dart will cripple the behemoth's legs, which will then allow you to stay with in flamer ranger.  Make sure you have plenty of fuel, and light him up.
