I found this for you on a trophy guide, I think that is all you need to know, good luck!
Perfect Freeflow 2.0
Perform a perfect combo including all of Batman's combat moves (any play mode)
This Trophy needs a bit of practice but nothing close to hard. In a Single Combo, you must use all of Batman'a Combat moves (Total of 12).
There isn't an easy way to do this to be honest, each one has his own way of playing. Use the Riddler's Revenge maps and choose the one you prefer. Note that Round 4 on the maps and perfect because these are the rounds that contain lots of enemies to help you get the Trophy before defeating them all.
Here are the moves that you must include in your combo:
Do all these moves in one combo to earn the Trophy. Note that moves with This Color needs a combo of 8x (5x with the Special Combo Boost upgrade) to do at least one of them.
Im good at the combats but its wen i try for this trophy id need maybe forget 1 or 2 moves
exactly, what I did is I looked up all the moves in the upgrade menu of the game, then wrote them down and tried doing them all in one combo, it's not an easy trophy that's for sure!
