Drone mines consist of a brownish sphere with a peg on above and below it, on the left and right, and as well as on the sphere. The pegs on the sphere have bright orange lights on them.
Drone mines appear in groups and explode if Takeshi touches one, hurting him in the process. They can also be taken out with a single ninja star. Inactive drone mines also appear in the level where Dr. Boshi is chased after for the first time. They are a lighter shade of brown, remain stationary and show all pegs on the mine. All mines can potentially pursue Takeshi if a tripwire laser is activated.
