Super Mutant Behemoth



A Super Mutant Behemoth is a giant 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. It is unknown how these particular mutants achieve this size, but if their numbers are any indication, it rarely happens. For that, the Wasteland can be thankful.

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. another good stradegy i used, was that i quickly ran under the building across from GNR and waited until my action points filled up and keep using vats, but while doing this the behemoth runs away but if you quickly walk out for a second he will come back to you.


 * In Evergreen Mills, the Raider-controlled train yard, a behemoth is trapped by an electric fence. The generator can be destroyed from a distance which will allow the Behemoth to begin attacking any nearby Raiders.  By far, the easiest method of defeating this behemoth is to defeat the raiders, lay several Bottle Cap Mines near the gate, but far enough away from the generator so they don't detonate when it explodes, and then release the locks on the cage.  Alternatively, the Behemoth can be attacked by ranged weapons through the mesh gate while the generator is still active. The roof of the nearby train car offers a clear view of him.  However, it is possible that the Behemoth may escape during the player's shootout with the Raiders, forcing the player to deal with him in the tight confines of the camp.  Another alternative is to  jump between the carriages to get to the other side of the carriages.  The behemoth will try to get through but can't and eventually will run off.  Just jump back over and it comes back, repeat until the Behemoth dies. Normally the Behemoth won't attack any followers with this method.

Note: On the PC version, the Behemoth might bug out of his cage if he spots the player or Dogmeat; as Dogmeat tends to attract enemy attention from a great distance, he is most likely to agitate the Behemoth before you do.

Note: Another bug has been found in which the Behemoth (when it gets out of the cage, by any means) will fight ALONGSIDE the raiders, making the battle considerably more annoying. Reloading the game to a point BEFORE it leaves the cage seems to solve this issue. It appears to be random.


 * A Behemoth can be found in the Capitol Building fighting Talon Company mercenaries at the west entrance. There is a considerable amount of fighting between Super Mutants and Talon Company so its best to just sit back and watch. After a bit you'll find the room under the dome and that is where the Behemoth is waiting.  He should be getting shot at by more Talon Company so just wait until he has low health and hit him with one nuke.  Then finish exploring the Capitol building.


 * A Behemoth is located southwest of the Takoma Industrial in Takoma Park. There is a truck near a water tower a few feet away. On the truck you can see a dead mercenary and a switch that activates some artillery that makes the fight a lot easier.

Note: The boxcar interior isn't a guaranteed shelter from attacks, but when the Behemoth first charges, he will come as near as possible, and if his view of you is blocked by the roof, he will be unable to attack. You can take free shots at him in this case, but any critical that causes him to stagger back will make it possible for him to see you and attack your confined location.
 * One final Behemoth is located at a Super Mutant camp, after following a series of search party notes (Freeform Quest: Finding Cheryl, see quest Search Party Log). The final note takes you to a camp between the Jury Street Metro Station and Evergreen Mills. Both are located due west of Vault 101. You do not need to get these notes to make this Behemoth appear. Keep going west from Vault 101 until you find Jury Street Metro Station. Head further west from there until you find a bunch of wrecked train cars along with a few Super Mutants. If you're having trouble finding it follow the tracks heading NE from Evergreen Mills. The Behemoth should appear after you enter a carriage filled with shopping cart. Locate two carts with a teddy bear inside and open the "cart cage". Finally taking you to the final location where the last (and hardest to find) Behemoth should have spawned. Bear in mind that you do NOT have to find the notes before opening the teddy cage for the Behemoth to appear. My level 8 character had a nasty surprise that way.

Note: You can wait up on the edge overlooking the train carts and wait 12 hours and the behemoth will appear, but sometimes Enclave soldiers may appear as well. They will ally with you against the behemoth but once he dies they turn on you. Fawkes can be helpful here as well.

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 20 feet tall Super Mutants. They have necks so thick with muscle that they merge into their bodies and extremely large build. Some Behemoths carry fire hydrants which can easily damage the player and swiftly kill any living being in their radius. The shopping carts on their back may provide some form of primitive protection to cover their thick and bulky hides, unlike other Super Mutants which have their own, albeit still basic armour. The shopping carts are also used to store live captives, but this does not appear in the game. Another point to consider would be the skulls linked together by a chain to form a necklace of victims, yet another intimidating feature to these already terrifying creatures.

Strategies

 * Never stay still as Behemoths are highly effective close combatants and will do significant damage from melee range. Moving backwards while firing is particularly effective. Never let yourself get cornered or stuck on terrain unless you want to be turned into a pile of mush.


 * Due to their large size behemoths cannot enter hallways or get under low hanging rubble and have difficulty getting around any large obstruction. The player can use terrain to their advantage to keep themselves out of melee range while gradually taking the behemoth down at a safe distance.


 * Behemoths are usually supported by normal super mutants. Give the guards priority, but keep moving to avoid being hit by the Behemoth.


 * An all purpose strategy for any ranged player is the Dart Gun which will cripple the behemoth's legs with a single shot regardless of the player's Small Guns skill. With the behemoth's mobility reduced practically any ranged weapon can be used to finish it off.  Care should be taken, a crippled behemoth can still deal massive damage if allowed to get back into melee range.


 * Big Guns specialists with a rank of 100 will find a perfectly repaired Fat Man does 1674 damage per shot and has a potential to knock the behemoth down. Using one mini-nuke and following up with the Minigun while the behemoth is staggering is a quick and effective strategy.


 * Small Guns specialists will find the Victory Rifle is also efficient and capable of knocking a behemoth down.


 * Laying land mines and luring the Behemoth through them is an effective tactic


 * If Dogmeat is still traveling with you, order him to stay in a safe place. Dogmeat's only attacks are close range melee and he can be damaged quickly by the Behemoth.  This can be dealt with somewhat with the dialogue option to use a Stimpak, which is available even during combat, but keeping Dogmeat out of melee range is safer.


 * Small Guns are highly ineffective unless aimed at the Behemoth's head. On the other hand, the Missile Launcher is quite effective at persuading Behemoths to die, and a direct hit to the head with a missile can knock off a decent chunk of its health, even if the launcher is in poor condition.


 * The Alien blaster and Firelance are particularly useful against Behemoths. With the quick rate of fire and high damage, a non-big guns character can take one down before it can get close enough to do any damage.


 * Due to their big size, it is relatively easy to achieve head shots in VATS. If the player has sufficient first-person shooter experience, it is also not too difficult to achieve head shots without VATS, assuming the gun that player is using does not have significant spread.


 * An Unarmed specialist can also fight them barehanded, though dosing on as much chemical assistance as possible is recommended. Behemoths are susceptible to knock-down criticals, though targeting their towering heads outside of V.A.T.S. is much more difficult. Targeting arms for critical strikes can reduce their impact and effectiveness. On hard difficulty, well-timed and frequent stimpack use will be needed to survive the brawl.
