Dr. Michael Kelly's experimental mind-transfer device could change warfare forever — and Micro Tech wants it. During a raid on Kelly's lab, the nameless Micro Tech brain behind the operation is shot and electrocuted, accidentally transferring his consciousness into Kelly's prototype cybernetic spider. The device is also permanently fused to his body. Now trapped in the form of a mechanical arachnid, he must crawl through labs, factories, the city, a museum, and the sewers to reclaim his body before Micro Tech's scientists find a way to forcibly remove the headset — likely with lethal results.
