 Another addition to the fighting force debuting in Halo 2 were Drones, or Yanme 'e (from the planet Palamok); the animators found the creatures challenging, as they had to be animated to walk, run, crawl, or fly on multiple surfaces. Old concept art from Combat Evolved was re-purposed in influencing the Drone's final shape, which took cues from cockroaches, grasshoppers, and wasps.
