Giant Ant (Fallout 3)

Giant ants (Mega Hexanta) are enourmous ants in fallout. They are usually found around hills and canyons, but they can be found semi-commonly around towns and in D.C too.

Build
Giant ants are quite muscular and mostly rely on melee attacks

They have five body parts: Antennae, left- and right legs, torso and head.

Head
Crippling this will lower their perception, like with all other enemies.

Torso
Crippling this will increase the chance of staggering (stunning) the opponent temporarily.

Left/right legs
Crippling the legs will slow them down. Same goes for all enemies.

Antennae
Crippling these will make them go into frenzy mode, attacking everyone and everything around them, even their own brethren.

Strategies
In order to bring down a giant ant, it is recommended to hit the head if possible. If you have a dart gun, you can cripple it's legs, making this much easier. If you're fighting a very strong ant (such as the soldiers and warriors), the dart gun can be essential at lower levels, especially if you're fighting fire ants. Crippling their antennae won't actually help unless there are other ants around, and even if there are, they will still attack you, not becoming your friends.
