Capcom vs. SNK: Millennium Fight 2000 is a fighting game by Capcom. It is the second game in the SNK vs. series, a video game series that features characters from Capcom and SNK games. This game utilizes a "ratio" system, in that the "ratio" is a rating of a character's overall strength, ranging from 1 to 4. Teams of up to four can be assembled, but their combined ratios must equal and go no higher than 4. The player also has their choice of "groove", or attack meter. The SNK groove is based on Extra mode from KOF '94 to KOF '98 and Capcom groove is based on A-ISM from the Street Fighter Alpha series.
