Guard Drone
The Guard Drone is an enemy in Atroxian Realm, a Keen 4 mod by Gridlock.
When Atroxus first captured The Sky Sanctum, a small expedition of Krile delegates was sent there to try and communicate with the Atroxian leader. They never returned. Upon reaching the sanctum, Commander Keen discovers the horrible truth: The delegates were massacred upon their arrival, and their lifeless bodies corrupted and reanimated by small three-eyed robots known as Guard Drones. The drones use blue energy beams to control the Krile's lifeless corpse, moving around very quickly and firing bolts of deadly blue energy. Keen's Neural Stunner has no effect on these tragic foes.
Guard Drones are not mentioned in the in-game text file, though they are a Berkeloid replacement.
