As far as I can remember
>4th tier upgrades to some weapons and armor, have fun grinding for purple metals to upgrade those
>new equipment based on Gravity Rush
>10 new floors for super endgame players, your only reward after fighting 10 floors worth of overpowered haters is 1 Purple Metal, and some other insignificant stuff
>4 new superbosses based on the 4 Horsemen
Other than these, nothing else of note.
