While not every Xbox 360 game receives a playable demo on the system's Marketplace service in a timely fashion, there are exceptions. In the final days of June, a demo for 3D Realms' first-person shooter Prey went up for download more than a week in advance of the final game hitting store shelves. Now 360 gamers are getting to go hands-on with another yet-to-be released game, as a 587.43MB demo for Ninety-Nine Nights is now available for download.

　　An action adventure game in a fantasy setting, Ninety-Nine Nights puts players in command of seven different characters as they hack their way through opposing armies. Developed as a collaborative project between Tetusya Mizuguchi's Q Entertainment and Korean studio Phantagram, it represents a bit of a break from tradition for both companies. While Q is known primarily for puzzle games like Lumines and Meteos, Phantagram earned accolades for its work on the real-time-strategy/action hybrid Kingdom Under Fire series.

　　Ninety-Nine Nights is rated M for Mature and will retail for $49.99 when it's released in mid-August. For more information on the game, check out GameSpot's previous coverage.
