From Sega Retro

Spikeout is a 3D beat-'em-up franchise created by Toshihiro Nagoshi under his division at the time, Sega AM11, and was continued by Nagoshi's later division, Amusement Vision. It started with Spikeout: Digital Battle Online, a 1998 Sega Model 3 arcade game and was last seen re-imagined as Spikeout: Battle Street. The franchise is notable for its multiplayer aspects - the original Digital Battle Online was the first beat-'em-up game to allow multiple arcade cabinets to be linked together. The series was pushed into relative obscurity due to Sega's reluctance to port the games to home platforms.
