Kick boxing is probably a good pick for beginners, followed by Streetfighting then either Wrestling or Submission as a third choice. Martial Arts sounds neat, but is fairly hard to KO people without a blazing grapple or an environmental-based throw (like head into a TV set).
Unlock Your Girlfriend's Blazin' Move
Early on in Story Mode, you will choose a girlfriend. A few fights later, you will have to choose between her and Carmen Electra. Choose your girl, and you will then control her in a fight against Carmen. If you Blaze her and win the match, you will unlock her Blazin' move. Also, if you lose, you do not get a rematch.
KO Without Blazin'
When the opponent is in the Danger zone, you can KO him by either hitting him with a weapon, grappling them up against a wall, or using the crowd in a double-team.
Martial Artist KO
When using a martial artist, get your opponent in the Danger zone. Then run up to a wall, or any object, and press P or K to jump and attack your opponent. If you connect, you can get a KO.
Streetfighter KO
When your opponent is in the Danger zone, attack them with a Haymaker (a Strong P) and you can knock them out.
Subway KO
When fighting Trejo in the subway, listen for the train. When it gets close, throw him onto the tracks. If he wobbles on the edge, just punch or kick him off. If timed right, the train will KO him.
