Radroach (Fallout 3)

Radroaches are creatures found in the Capital Wasteland in 2277.

Background
Great American cockroaches, colloquially called "radroaches" or simply "giant cockroaches", are giant versions of the pre-War species that have increased in size presumably due to the nuclear fallout 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. They are very territorial organisms and will attack most, if not all, things that pass by. This often leads to their death as they are not very durable adversaries.

Gameplay attributes
Radroaches are low-level enemies, hostile to the player. They are usually encountered in groups of 5-7. They "pounce" at their enemies and bite/pinch them with their small pincers while making a skreach-like sound.

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

Appearances
Radroaches appear in Fallout 3.

Behind the scenes
There is a theory that present-day cockroaches would be able to survive a global nuclear disaster.
