The next day, Mystery, Inc. themselves come to the college and learn from their friend Eric that the virus had assumed a lifelike form thanks to an experimental laser able to transmit objects into cyberspace, and is now running rampant across the campus. The gang goes on the hunt for the Phantom Virus, leading to it chasing Scooby and Shaggy throughout the campus. Unfortunately, the whole gang, including the virus, is banished to the game after an unknown person activates the laser. Left with no other choice, the gang fights their way through the ten levels of mystery and adventures to complete the game in order to escape it, with the goal of finding a box of Scooby Snax to complete each level. The Phantom Virus, meanwhile, attempts to impede their efforts on each level.
