Giant ant

Giant ants are hostile creatures commonly found in the wasteland, including the American Southwest, the Capital Wasteland, the Mojave Wasteland, the Commonwealth and Appalachia.

Background
According to the Enclave field research terminal entries, the creatures of order Hymenoptera, family Formicidae, and genus Camponotus were exposed to large levels of radiation, growing larger.

Large and small forager ants make up the bulk of the colonies.

They may frenzy if their antenna is damaged.

Giant ant queen


A queen is larger than drones and soldiers. When threatened, she buzzes her wings and will hiss at the enemy. She will then proceed to spit an acidic saliva at the enemy in an attempt to ward them off.

Giant soldier ant


These are the colony's main defense against intruders. They are plentiful and can often overwhelm an enemy by either running it off or killing it. This ant can often be found accompanying smaller ants as they forage.

Giant worker ant


These ants do most of the work around the colony.

Invader ant


Two of them may be found attacking the mutated forager ants in Shalebridge tunnels.

Mutated forager ant


They are friendly and won't attack, even if they are attacked.
