* Easy wins in Career mode
Go to the options menu and set "Illegal Blows" to "Off". Then, go to the fight store and buy the illegal head punch called "Elbow Shot". During a fight, use the Elbow Shot to counter attack each time your opponent throws a punch. Note: Make sure you use the Elbow Shot as a counter attack so that you can connect cleanly and powerfully on you opponent’s head. You will see that the Elbow Shot inflicts a lot of damage to your opponent, and will KO him in a short period of time, or TKO because you inflicted so much damage to his eyes.
* Remain undefeated
During any fight in Career mode, if you get knocked down and you think you are not going to make it, turn your PlayStation 3 off before the bell rings. When the game is resumed, you can start the match again without a loss.
