WCW/nWo Revenge
Limited Invincibility
While in any match-up, walk over and stand right next to any opponent. While doing this hold C-Down. If you are close enough to your opponent you will just stand still. If you do this correctly and your opponent tries to punch or grapple you, he will go right through you.

Playing Dead
When you get knocked down, hold the analog stick down and you will stay down on the mat until you let go. This good to surprise unsuspecting opponents.
