just picked this up. i am having some problems with pulling off finishers. i know you hit a+b when you have a block filled but, does the opponent have to be stunned or something? thanks in advance!

Don't have to be stunned. They just have to be in the right position. You can have up to four finishers depending upon the wrestler you are using. For example Austin has the stunner and the million dollar dream. You do the first by hiting AB from the front, and the second by hitting AB from the back.
