Many renowned martial artists have registered for the tournament. People around the world focus intensely on the upcoming exhibitions, making long-awaited opening ceremony a huge success. The game uses a "ratio" system which means a rating of a character's overall strength. It ranges from 1 to 4 and no farther. Teams of up to four can be assembled, but their combined ratios must equal and go no higher than 4. The gameplay uses the SNK-style four button format, in addition, the player also has their choice of "Groove" which is another word for attack meter. The SNK-Groove is based on Extra mode from The King of Fighters '94 to '98 series, while the Capcom-Groove is based on the gameplay system from Street Fighter Alpha.
