Super Rats

 Super rats  are one of the several corrupted animals that wander through this destroyed land, they are roughly 3 times bigger than their old selves and obviously very aggresive towards other species mainly not-corrupted ones, even though they are not a big treat to a human with decent gear, their high numbers and reproduction rate makes them one of the most dangerous pests of the Wasteland.

Behavior
They are much more aggresive and resistant than normal rats or any other rodents. Being strong enough to resist two 9mm rounds to the body and usually surviving atleast one headshot...the Alphas are way more resistant being able to survive atleast 6 shots from low-calliber-rounds.

They usually form colonies at dark and humid places such as sewers and caves/mines, interestingly the males are bigger than the females, this is the exact oppost of normal rats and rodents

(Know) Species
1-Browns: The most common species, an individual is not a treat to any armed person, but their high numbers are the reason of the fall of many settlements.

2-Tanks: Slightly bigger than the  Browns  and are much more resistant than all the other species, but their reproduction rate is slower. So don't expect finding high numbers of them at  young  colonies.

3-Diggers: Very weak, but overrall faster than all the other species combined, trying to destroy one of their colonies without heavy weaponry is basically an One-way-trip.

4-  Dwellers  : Not many is know about them, since they are an exclusive species of Bunker63, they are also responsible for the destruction of the Bunker. They are trapped inside the abandoned shelter with no way out but according to the Bunker63 survivors these are the most powerful and dangerous rat to ever exist. Being strong enough to break thin sheets of metal with their teeth, and in such high numbers that they can eat a whole person in 2 minutes.
