The game has a normal single player mode, a survival mode, a two player vs. mode, a training mode and a team battle mode. In team battle, you choose a number of characters and fight against a group of the same size controled by the CPU or a second player. You start with the first character and fight a one-round match against each character of the other group. Your health is not restored after a fight. If you loose a fight, you continue with the next character you chose.
The game lets you choose between Fighting Vipers style or Virtua Fighter style controls. You have a block, a punch and a kick, and the ability to evade on the third axis.

By beating course, you unlock both new courses and new characters. The game has a roster of 32 characters altogether.
