Ant (Fallout 3)

Ants are creatures found in the Capital Wasteland

Background
A scientist named Mackay theorized the ant mutation came from the effects of extended exposure to radiation. Giant ants have retained a strong swarm instinct and will attack prey in packs or double-down to protect the nest if their queen is threatened.

Gameplay
There are five variants, including workers, soldiers, queens, invaders, and the mutated forager ants. Ant nectar can occasionally be looted from their corpses and refuse piles found in their lairs.

Ants usually attack head-on in droves of up to five. They do not try to flank enemies but will surround them if they get close enough. If their antennae are crippled, ants will frenzy and attack everything around them, including their own kind. The Entomologist perk will increase damage against giant ants and other insects by 50%.

Behind the scenes
According to Mark Lampert, the sounds for the giant ants were created using various plastic wrappers, clear wrap and liquids.

Bugs

 * A glitch may occur where once the Lone Wanderer kills the fire ant nest guardian and leaves, the Marigold ant queen will glitch/crawl through a wall near the exit and stand in their way, trying to attack them. With some effort, one can either jump over her legs to the side and escape or kill her.
 * There is a glitch that may occur when getting close to the first defeated nest guardian where the queen will teleport to the player's location.
