For this achievement you must complete 10 Ranked
matches on the winning side. What I did for this achievement was become really good with just one character straight away. I used Superman for this achievement as I had started the S.T.A.R LAB missions as him and slowly learned all of the combos that allow me to "juggle" my opponent in the air.
8 - UP
6 - RIGHT
2 - DOWN
4 - LEFT
(X) - X button
(Y) - Y button
(A) - A button
(B) - B button
(LT) - LEFT TRIGGER
(RT) - RIGHT TRIGGER
+ - preform simultaneously (at the same time as both the letter and number)
(I will use the number pad for the directions and the letter for the button) Some moves that you're going to want to memorise are 2 6+(X); (X) (X) (X) for right after you lift them into the air and than 2 6+(Y). Also if they like to block down when you try to start the juggle just use 6+(A) to hit them in the air. You can also use his heat vision 2 4+(X); and when you have your supermove use 4+(A) to kick them then use (LT)+(RT) when they're just about level with your punch. This will start your 8 or 9 or 10 hit combo. This will take time to master that combo but you will eventually get it down pat.
Well I hope these tips help you out. Love all you TA'ers. Have fun beating up your favourite villains and heroes and keep on achieving
