It took me a long time to get it right (mainly the Stage flame timing lol) but I got it right! The moves are as follows Undertaker 2 (intro), Kane (stage), Kevin Nash (ramp), Kane (ring in), Kane (ring)
I tried it and I still like Kevin Nash more. It has a more deliberate pace than Brock, plus the hand taunts are nearly perfect for Kane grabbing his glove or wrist.
this is on PS3. Im not sure what you mean by slow it down. You have to play with it a little because the timing you see in the Create an entrance portion is about half a second off so what I had to do was play a match, watch the entrance and see if it was in cue with the music. hope this helps
