Cadaver Beetles are a species of scavenger insect that help to keep the planet Helghan clean of deceased creatures. The beetles feed on the dead and move in quickly to devour any fallen soldier, ISA or Helghast alike. They pose no threat to the living, but do provide a valuable service to the Helghan ecosystem in cleaning up the remains of those that have fallen in combat. Cadaver Beetles seem to be a common sight on Helghan, inhabiting environments ranging from the sewer systems below dense cities, scorching deserts, and even hostile, humid jungles.
