In addition to providing tracks, all nine members of Slipknot appear in-game as unlockable characters for use in either single player or multiplayer modes. 3volution Studios, co-owned by Raymond Herrera, drummer of Fear Factory, will be responsible for creating all the sound F/X and recording voice-overs for Infected.

“We’ve compiled music from some of today’s hottest metal bands to create an in-game soundtrack that perfectly amplifies the hardcore, fast-paced game play experience of Infected,” said Ken Gold, vice president of Marketing for Majesco. “Players’ pulses will pound as they attempt to complete intense missions while being shredded by the bone-crunching sounds of some of heavy metal’s finest bands.”
