Spikeout: Battle Street

Based on the 3D coin-on arcade title of the same name, SpikeOut: Battle Street offers a quick single-player mode that's about two to four hours long and each time it's beaten, a new character, with slightly different special attacks, opens up.

There are around 10 levels, and 12 unlockable characters, and an online mode. You can connect with three other players for a four-player online bout on Xbox Live, and as a "sort-of" team, you then proceed to smack infinite nameless thugs into polygonal paste.
