The Copter Drones may be placed in the Drone Silo.
When placed in the Drone Silo the Copter Drones become one of five Aircraft able to be used in Defense of the Player's Base. The other Aircraft are : Wing Drones,Reaper Drone, Slayer Drone and the Halcyon.
Copter Drones receive a 100% Speed increase at Level 10. This high Speed combined with its low Space Requirement commonly prompts players to keep at least one in the Airfieldas a Bait Unit.
Level 10+ Copter Drones with a speed of 2.6 are the second fastes moving Hover Aircraft behind the Reaper Drone with a speed of 3.0 with a tie speed of valkyrie level6+.
A Level 10 Airfield will hold up to 40 Copter Drones.
The Copter Drones and the Wing Drones are the only units in the game referred to in the plural.
Advantage: The large number of Copter Drones that can be deployed makes them a very big threat to the Flak Turretand Stinger ( both in and out of Watchtowers ) if they are spread out to form a 1/2 circle when Attacking. This allows the damage from these defenses to be limited to relatively a few units.
Disadvantage: Copter Drones have a roughly 1 sec pause in firing about every 3 sec. This allows defense units to either get into range or to come to a stop and fire.
In Game Graphics show the Copter Drones and other helicopters violently spin out of control and exploding when they are shot down.
The Copter Drone has 4 circular propellers, 2 "eyes", and 1 Machine Gun. The Reaper Drone has 2 circular propellers, 4 "eyes, and 2 Machine Guns.
