First, select your character from the roster, each with unique skills. Move your character with the directional buttons and vault with the action button. Strike your opponent using the X key and activate unique abilities with the O key. Your objective is to overpower the other combatant by reducing their HP. Coordinate your moves and parries carefully, as each character has different speed and strength. Monitor your opponent's habits to predict their next action. Succeed multiple fights to demonstrate you are the toughest on the street.
