Buggers/Drones – Halo Series
These guys would be fairly standard Covenant enemies, but they have been given the ability to fly. They’re not particularly tough, but they move around so erratically that they’re a major nuisance, particularly since they usually appear in waves. It’s important to focus on them because they’re so quick, but while you and your marine buddies are running around looking up, chances are good that Covenant ground forces are preparing to give you a plasma grenade-shaped wedgie.
