Corpse eaters attack in swarms in a manner not unlike rakk, but are much harder to shake off. They make several attacks before backing off for another pass. Like rakk, they are quite fragile and will usually die to the first thing that hits them. As such, shotguns and certain area effect attacks have been found to be very effective against them.
