Spikeout: Digital Battle Online

Spikeout: Digital Battle Online is a 3D beat 'em up video game developed by Toshihiro Nagoshi, and released by Sega for their Model 3 Step 2.1 arcade system board in 1998. An update, Spikeout: Final Edition, was released in 1999.

A follow-up, Slashout, which was a slash 'em up set in a medieval fantasy setting, was developed and released in 2000, also for arcades. A spinoff, Spikers Battle, adding a versus fighting element, was developed and released in 2001, again for arcades. Another follow-up, Spikeout: Battle Street, was developed by Dimps and released exclusively for the Xbox in 2005. A new port of the first game is about to be featured in Like A Dragon: Infinite Wealth for PlayStation 4, PlayStation 5, Xbox One, Xbox Series and PC, alongside a new port of Sega Bass Fishing.

The SpikeOut games bear a resemblance to Sega's earlier Streets of Rage series.
