Biggest combo:
Press Square(2), Triangle, Circle, X(3) for the Corporate Punisher 2 attack.

Easy wins:
As soon as your opponent gets back on his feet, execute a punch combo. You only have a small amount of time to hit him when he is not blocking you. Kicks do not work as well, as they usually duck faster and can sweep you on the ground. A good combo would be Square, Triangle, Square, Triangle.

Opponent fighting styles:
A martial artist is a fast punch and kicker. Brawlers do heavy damage with grapples, but are very slow at punching/kicking. The other types are a mix of these two and have respective differences, such as heavy punch/kicks but slow punch/kicks, etc.

Alternate victory pose:
Immediately after you fight Lou in arcade mode, your character does a little victory pose. However, when you defeat him using a martial arts fighter (for example, Tyler), you will gather electricity in your hands. As your character is finishing it off, he generates electricity in the palms of his hands.
