Missile Drone

Missile Drone (unofficial name) is a new enemy introduced in The Ninja Saviors: Return of the Warriors.

Details
This enemy appears as a robotic flying drone with four propeller engines which carries a pair of missile launchers. It always floats close to the top of the screen, out of the reach from the player's regular attacks, floating down to launch a barrage of missiles diagonally downwards. They always appear during boss battles depending on the game's difficulty.
