The heart of Capcom vs. SNK 2 was its "Groove System"—six different fighting styles (C-Groove, A-Groove, P-Groove, S-Groove, N-Groove, K-Groove) borrowed from various Capcom and SNK franchises. Evolution Rev 2 not only preserves this system but enhances it.

Online communities still run tournaments via or Zetaboard using this very build. Every year, the MUGEN Anniversary Tournament features a side bracket for Evolution Rev 2 .
