Drones often emerge from conduits throughout the game. They're humanoid creatures that carry weapons, most notably the Drudge weapon called the Strike Rifle.
Early designs of the Drone during The Conduit's production had a different look than the one that actually appeared in the finished game. It was changed before the game's release. The early Drone design was more red and black colored and was less bulky. Many of the game's screenshots that were revealed before its release showed the old design.
