Interference:
Press Select during a match. Another wrestler will appear and interfere with the match.

Special ending:
Complete the game with one of the programmers for a special ending followed by FMV sequences for all the characters.

Mid-air fighting:
Select a character that has a special move that may be executed when the opponent is running, such as Hollywood's Big Boot. Begin a match and slam your opponent so he does not get up. Climb on the turnbuckle, and wait for your opponent to get up. When your opponent runs, execute your character's special move once. If done correctly, your character should be floating in mid-air. Move towards your opponent and try to force him on the turnbuckle. Move next to him and he should slam your character in mid-air. Note: The game will freeze if your character leaves the ring. An alternate version of this trick results in a "Quicksand" appearance. Repeat the trick until your opponent is on the turnbuckle. Wait for him to jump off, then press Punch or Kick to jump. If your opponent successfully hits, your character will appear to have sunken into the ring.
