Oh, I'll just add something in here. Combat drones designed for melee and close quarters combat. Sure, the flying drone with the sniper rifle is nice, but especially in urban and jungle environments, having a drone capable of fighting in melee would be useful. Hell, Deus showed how effective melee drones could be with the Spiders and Medusas, as well as the bumblebee with its nanobot sting. I can't imagine that the tech has gone completely.
