what does 5x 2x etc. mean? i'm not really familiar with fighting game terms and i also have no clue how to use a super lol
its fighting game notation (and here X is just the button you press so A B or C)
so it is Neutral A B or C Down A B or C Forward A B or C and A B or C in the air
in terms of supers you have to do a half circle motion input C with meter
It's a number pad notation, so think of it like a numberpad on a keyboard, with 5 being the center, so if you held down, you'd be at 2, right to be at 6, left to be at 4, etc.
