Since this wasn't posted here yet I will do...
When you choose a variation just tap UP two times and then press Y/Triangle. Some seem to have a full moveset this way like Kitana.
Thanks for this! I didn't know about this. This might actually be useful for my Liu Kang because there is no variation that has the quick fireballs (dragons fire is slow because you can charge it) AND bicycle kick (flame fist has quick fireballs but no bicycle kick). Thanks
It's kinda a fun feature if you wanna play a character the vanilla way. Pretty neat. ^^
Also, it shows the costumes WITHOUT any of the Variation indicators. I quite like that.
