sounds like youre new, yeah itll be tough because it is the hardest combo to do in there, but keep at it, you shouldnt have any problems.

Its the timing. Try to slow down when you enter raiden's second stance.

Mission #9 is the hardest lessons of each warrior. To become a true warrior of Mortal Kombat, you must successfully complete mission #9.

Now with Raiden, the biggest combo in his mission is:

B, B, Y, L Trigger, B, A, L Trigger, X+Back, Y, X

(10 hit combo)

Remember, you are putting combos from each style into this huge combo. Slow down, but don't stop pressing those buttons....LOL

dude, listen to me. it is much easier to perform the combo you are having problems with if you do NOT, i repeat, do NOT look at the screen at the time you are doing it. i am not joking. just memorize the button combination and while doing it, instead of looking at the screen, look at your controller. that will help. looking at the screen distracts you.
