At the wrestler selection screen immediately before a match, press L or R to use a
superstar's alternate costume.

Run at the ropes and press Analog-stick Away + B from them. Make sure to aim correctly.
The person should be near the ropes to your left. It helps to get them stunned on the
ropes first.

Play revenge mode until you get to the last mission. When you complete the mission,
whoever you faced will available for exhibition mode (for example, Han Zo Mon, Kim Chee,
etc.). Also, complete Revenge mode several times. Each time you will get a random new
Boss. After they are defeated, they will become unlocked. Additionally, once you complete
each stage (for example, Shopping Mall), you will unlock a Boss and some Revenge stages.
Note: You will have to do this on each stage to eventually unlock all the Revenge stages
and Bosses.

Get your opponents weak enough so that when you throw them off, they will not hang on. Go
to the top of the Hell In A Cell, get the opponent weak, then throw him off near the
announcers tables.

Select someone such as Brock Lesnar or Scott Steiner. You have to eliminate security by
making them bleed. This is where the F-5 (or if you selected Scott Steiner, his signature
move) is useful. Those two signature moves usually make the security bleed after a few
times. If this does not happen after the signature moves, Irish Whip them to the glass,
get the crate and mop, and continue hitting the opponent.

Change Kurt Angle to a "BabyFace" in the customize feature. The crowd will not chant "You
suck!" during his entrance. This also applies to created wrestlers who use Kurt's music.

This is basically a handicap match. Run away from the security guard and go down the
escalator. Once there, you will find a wrestler waiting for you. He or she will approach
you and join the security guard in fighting you. Try to get one down, then Irish Whip the
other onto the garage/cell structure. Continue doing this. You can knock them both down,
than start attacking the garage/cell structure as well. If timed correctly, you can get
this done in at least five minutes.

When you and the person you are facing are both outside the chair, pull out a chair from
under the mat (or play a TLC match and grab the chair). Put the chair down and Irish Whip
your rival onto the table. Press Y while holding the chair to get on the table. Wait for
your opponent to get up and press to do a DDT on a chair through the table. Note:
You be someone who has the DDT on a chair (for example, Rey Mysterio).
