Nerble Force is a clone of the arcade smash, Defender. Although fairly low resolution compared to some other clones, the opponents and their behaviour is one of the closer clones the Coco had. This includes the landers that change to mutants after stealing humans into space, swarmers that split into multiple smaller ships when you hit them, bombers and leave a trail of bombs behind as they move, and others.
