Contest starts tonight and ends November 21st 2010.

"For every 250,000 hours that Raptr tracks collectively for Call of Duty: Black Ops play time (for PC and Xbox 360 only), a new prize will unlock so that a randomly selected eligible entrant can win. Raptr is also unlocking prizes at an individual level. Gamers can be automatically entered to win more prizes based on how many hours they play individually.

To be eligible for a prize pack, gamers just need to head over to Raptr’s contest page and register at http://raptr.com/contest/codbo. Current Raptr users simply need to register to enter. New users to Raptr should also download Raptr’s award winning app to track their gaming hours.

Entrants can win one of over twenty prizes including: Alienware PC hardware, Xbox 360 Kinect, PS3 Move, Logitech gaming peripherals, Gunnar eyewear for gamers, Activision games, Splitfish Pirahna Controllers, Primal gaming headsets, and a swag bag from TheKartel.com. Residents of legal age from the United States and Canada (excluding Quebec) are eligible to enter.
