The engine uses 4 directional keys along wih 7 buttons for gameplay (X, Y, Z, A, B, C and Start), in order to accommodate six-button fighters which use three punches, three kicks and a start button. However, characters do not necessarily use all seven buttons, nor need to follow a traditional six- or four-button format.
At most, two human players can control characters, with others being controlled by the engine's AI (including Watch Mode, a demo mode where the computer controls all characters).
In addition, several gameplay modes are available via the main menu.
