Rodexes are quick little creatures which travel in packs. They don't do much damage with their attacks, but should they surprise a foe they can hurt it aplenty. One ought to listen for their squealing upon entering a room. As seen in many other smaller pack-hunting species, Rodexes are a cowardly bunch and tend to flee from fair fights. Good ways to take them out is to punch holes in them from a distance with an M-343 or the Alien Assault Cannon.
