Among several online game options is an exclusive mode called "Quarter Match," a new way of reliving the exhilarating arcade experience at home. Xbox 360 users can access Xbox Live Arcade to download a free, feature-limited version of the game which offers two playable characters for one match. When you're ready for the ultimate retro gaming experience, unlock the full version of the game and choose from all eight original characters as well as four boss characters, each with their own special endings and home levels.
