Zoinks! The Scooby-Doo crew get into a whole heap of trouble when they visit their old friend Eric Staufer, a computer science major at the university. Eric has invented a laser that can transport people between the real world and cyberspace.
In order to test the laser, Eric and his friend Bill have designed a video game featuring Scooby, Shaggy and the rest of the gang. During the test, they accidentally unleash the Phantom Virus that begins terrorising the entire university. The gang agrees to help hunt down the virus, but when they're lured back into the laboratory, Scooby and the whole gang are beamed into cyberspace.
This is where you come in, as you help the gang as they travel through the game. Are you brave enough to fend off the villains? Are you clever enough to find the box of Scooby Snacks on each level? Can you put all the clues together to figure out who is responsible for unleashing the Phantom Virus?
As Scooby is wont to say in this type of situation, "Relp, here we go again!"
The double helping of Scooby snacks is completed by Mystery Mayhem. Presented just like your average TV show episode, complete with chattering knee caps, canned laughter, Scooby Snacks and sporadic sandwich-building, the game takes the form of a side-scrolling platformer, in which players take control of both Scooby and Shaggy and help the team look for clues and solve puzzles.
In this particular adventure, the quest is on to uncover as to why a certain mega industrialist by the name of Travis Sherman is forcing people to sell their land to him, and also to investigate the role that his occult-obsessed assistant, Selena Jones, has in these plans.
The game takes players to six spooky locations, including the likes of Hambridge University, Milton Bros Movie Studio, a Wild West theme park, and an eerie island. Each location is made up of around four levels and, in classic style, concludes with a big scary boss encounter. Throughout each level, Shaggy and Scooby must run, jump and sneak their way through, hiding from ghosts and collecting an assortment of clues, Scooby Snacks and food - the latter with which they can build gi-normous sarnies that go on to serve as extra lives and unlock bonuses.
