Radroach (Fallout 3)

Radroaches are creatures found in the Capital Wasteland in 2277.

Background
Radroaches are mutated cockroaches that have increased in size due to atomic fallout caused by the Great War.

Biology
Radroaches are about the size of cats with a shiny brown carapace. Unlike their modern day cousins, they don't mind the sunlight and will often be encountered in well lit areas, such as out in the open near the tepid sewer. Though the ones in Vault 101 seem to be afraid of light like their real world cousins.

Gameplay attributes
They are generally little more than a nuisance to Armageddon survivors and are less than likely to pose a challenge. Radroaches are territorial and rather aggressive, but not very harmful. Anyone can kill them with their bare hands. Essentially any weapon (including fists) can kill this insect instantly. It is interesting to note that because Radroachs are mutated by the Great War, they can get past the sealed vault 101 door, when the vault is supposed to keep mutation at bay.

Statistics
Radroaches all share the same vital statistics, but can differ in aggressiveness and confidence.

Appearances
Radroaches appear in Fallout 3.

Behind the scenes

 * Radroaches were apparently put in the game in response to the theory that present day cockroaches would be able to survive a nuclear apocalypse.
