Stalcraft Wiki: Ratcatcher Exoarmor

In-game description (EXBO)

Like the other diggers' armor, Ratcatcher was created from various scraps given a second wind by black diggers. The repaired and modified exoskeleton not only possesses decent mobility but also enables its owner to carry away any goods found in the Zone.
