Radroach (Fallout Shelter)

Radroaches are creatures that appear in Fallout Shelter.

Background
Radroaches, also known as Great American cockroaches or giant cockroaches, are giant versions of the pre-War species that have been mutated by radiation.

Gameplay
Radroaches are the weakest enemy in the game, and can be encountered both while exploring the wasteland and during incidents. While they are not very strong on their own during incidents they attack in numbers, and can cause trouble for ill prepared Vault Dwellers.

Radroaches can also be encountered during quests. Their boss variant is stronger, tougher and constantly deals radiation damage due to their glowing appearance. It can also call for reinforcements by wriggling its body.
