Reward: $50 +1,000 Respect

Bonus Condition: Knock out Kelly in a fair boxing fight

Bonus Reward: $10,000 +50,000 Respect

It is interesting what the game considers a "fair" boxing fight. When you are fighting Kelly, you shouldn't pull out a gun and shoot him in the face, but you should pull out a melee weapon such as a lead pipe or baseball bat and KO him with that. You will still earn the bonus condition. You can also use this technique in any prize fight in the game for a few Gamerpoints.
