This guide contains all the locations of the “Supermutant Behemoths” for the Xbox 360 achievement “The Bigger They Are…”.
1) GNR building, part of main quest where you meet Three dog in the second story mission
2) Capitol Building, go in the west entrance, and either follow the Talon mercs or just make your way in further, it’s in a giant circular room with a bunch of Talon mercs taking potshots at it.
3) Evergreen Mills- Outside, in this cage thing. Take it out quick, it can escape the cage. west of vault vault 112 you will see a little notch on your compass
4) Tahoma Park, Go towards the other Tahoma area (I can’t remember what it’s called… the Tahoma building) When you reach the building, there’ll be some Talon mercs there. You can kill them if you want, but don’t go inside the building. Instead, hang a left and loop back towards Takoma Park. The Behemoth is there with 2 super mutant brutes. Tahoma’s in the DC area, on the very right hand side.
5) West of Jury Street Metro- Head west, and look towards the sky. You’ll see a bunch of birds in the air. Head over there, there’s a bunch of crumpled up trains. Explore this until you see a little teddy bear trapped in a shopping cart cage. Open the shopping cart cage, take the teddy bear, and turn around. The super mutant should be barreling down the hill.
