 Easy knock downs
 
 In movie or any other mode, when the fighter approaches you at the 
 start of the fight, hit him with your special power punch. When 
 he comes to you again, hit him with another special power punch, 
 then attack him with body shots. This will drop his strength and 
 let you knock him down repeatedly, thus winning the fight.
 

 Super Punch

 If at any time during the game your blue meter is high, or your opponent gets
 dazed and shakey, tap the R1 button then a punch button. Your player will
 perform a super punch that usually takes the enemy out in one blow.
