In addition to several offline modes and numerous leaderboards and achievements, the game takes advantage of the new online features of Xbox 360 video game and entertainment system from Microsoft and the console’s powerful processing capabilities to create a seamless online multiplayer experience. Among several online game options is an exclusive mode called “Quarter Match”, which introduces a new way of reliving the exhilarating arcade experience at home. Xbox 360 users can connect to the Xbox Live online game service and access Xbox Live Arcade to download a free, feature-limited version of the game which offers two playable characters for one match. When they are ready for the ultimate retro gaming experience, users can then unlock the full version of the game, enabling players to choose from all eight original characters as well as four boss characters, each with their own special endings and home levels.
