When talking about Kingdom Hearts 3 we heard the only DLC would be the secret ending so they can avoid spoilers. Now though we get word that there would be no remix but there will be DLC.
So far we know of rage mode and critical mode. Critical will be more difficult with rage giving Sora a different form that has him going berserk and not just into darkness. The team hopes to finish the paid DLC before 2019 ends. As for what is next after that we don’t know.
This is due to Nomura being booked with other projects as the team is set to work on something next gen or wish too. What this means is that the stuff such as Organization XIII human names as well as other small stuff fans are craven for to be answered will have to wait another time.
