Stalker: Shadow of Chernobyl
Stalker: Clear Sky
Stalker: Call of Pripyat
Determining the species from which the Zone’s rodents developed has so far proved impossible although it can be said with certainty that their ancestors were gregarious mammals. Although these animals are similar with jerboas in appearance, there is no relation between them. Although some stalkers like Inquisitor, a mutant zoo keeper, refers to them as jerboas.
As evidenced in X18, it is suggested a good number these rodents were originally test subjects before the Chernobyl incident. After high dosages of radiation transformed these beasts into what they are now, the mutated rodents most likely escaped and wreak havoc in the Zone.
Rodent is an quadrupedal animal reaching up to 40cm at the shoulder. They have large claws that can scratch big marks into Stalkers. Having frail and boney bodies, any weapon will do in disposing of them. Almost all hair has fallen out and only tightly wrapped skin can be seen.
Behavior and biotope
Rodents are more mobile, aggressive, and ravenous than the normal desert animal. They live mainly in basements and destroyed buildings while feeding on everything they can get their teeth in, from plants to careless stalkers. It is not known if other mutants attack or eat rodents, but both their bones and dead bodies can often be seen around the entrances to burrows that some mutants use. Sometimes, rodents attack and kill big animals and mutants in a large group, tearing them apart before they can escape.
