WWE SmackDown! vs Raw 2007 (PS2, Xbox 360, PSP)

Easy wins
To get an easy win in most types of matches all you have to do is grab your opponent in a strong grapple and drag them over to an environmental hotspot and perform the move. Regain your stamina and repeat until your opponent is weak enough for a pin.

Spooky...
In the Parking Lot Brawl, Irish Whip your opponent into the hearse. Press up on the right analog stick, and The Boogeyman will be in the hearse.
