Throughout gameplay, players can learn re-programmable fighting combinations based on five different brawling disciplines—Boxing, Wrestling, Kick Boxing, Tae Kwon Do and Jeet Kune Do.

The first nine are random, and the final two are always the same: Hardcase, a supposedly disgraced man as he wears a cloth which covers his mouth and has scars on his body; and Mask, a man whose fighting style is dependent on the player; if the player is a street boxer, he is a street boxer too, etc.

He/she wins twice and then the protagonist is taught how to make money, and he/she has to do the following: Fight to win, pull off a comeback con, start like a loser and make a comeback, and take a dive, start like a winner and then lose.

Team (name) fight to get invited to the Big Time, where the winners of the tournament get 10 million dollars.

Once they get to the Big Time tournament, the gang talk about the protagonist, but Kuro remains confident that Shades will take care of that team.

Still, they defeat team Menace and bring home that prize money, and Kuro is arrested.
