In halo 2 and halo 3 they were a kind of undiscovered enemy. Every now and then pop out of a pipe and shoot at you but never stuck around long at all. Halo 3: ODST change my opinion on these enemies forever. It wasn't so much the campaign however these enemies ability to drain your stamina and kill you with a PLASMA PISTOL is unheard of. Now thats not even the worst part, there ability to fly is the worst most annoying feature. It just makes me want to pull out a can of round up and shoot my Tv until it caches fire or the fumes kill me. They don't feel like formidable foes, more like the covenants pest control problem they don't feel like dealing with themselves. They should NOT keep these horrible enemies in Halo: Reach. If they did however i would like to see some vast improvement of the AI controlling them. I hope you enjoyed my rant about drones and how much i hate them. If you feel the same way i do please leave a comet. If you DON'T feel they way i do please leave a valid reason why you think i'm wrong. Thanks!
