Real names:

Hint: High Spot bonus:
Do moves such as the Super Kick, Inverted Stinger, Stinger, or Mounted Punches until you get the bonus.

Hint: Extreme Damage bonus:
The easiest way it to get the Extreme Damage bonus is to do a submission move such as the Sharpshooter.

Hint: Weapon Damage bonus:
Grab and hit your opponent with a weapon (press Up outside the ring).

Hint: Bloody Match bonus:
Turn on "Blood" in the options. Hit and stomp on your opponents; especially their head.

Hint: Ref Bump bonus:
Get a weapon, and when your opponent is down, try to get behind the ref. Swing your weapon as if trying to hit your opponent and he should go down.

Hint: Move Variety bonus:
Mix up your moves; for example a Grapple, Stomp, then another Grapple.

Hint: Reversal bonus:
Everyone has some sort of suplex. Go for your suplex (for example, Corkscrew. This is the most countered move). When they counter, try to counter them. After you counter, keep going for highly countered moves until you get reversal bonus.

Hint: Finisher bonus:
Try to get a finisher that is executed from the front because those are the easiest. Get your opponent up, and wiggle the Analog-stick quickly until you execute your finisher.

Hint: KO bonus:
Beat up your opponents until they KO. They should KO after about six moves after all their health is gone.

Hint: Increase SmackDown meter:
During a match, you can quickly increase your Smackdown Meter until it is full, by pressing Taunt. If your SmackDown meter is almost empty, you will have to repeat this a few times. After every taunt, you will see your meter grow a percentage until it is full. Note: When performing a taunt, it leaves you open for your opponent to attack. This is best performed while they are either groggy or on the opposite side of the arena.

Hint: Skip matches in career mode:
When you are in a match in career mode, select "End Match" and you can then go on to the next arena without fighting that match.
