Hi

I'm trying to buy the true ending chapters but can't see them available?

I've finished game but with no S ranks. So no alt ending. Is there anyway to download the chapter 19 + for the true ending or do I have to get the S ranks to finish the alt ending and then that enables me to buy the DLC? Not clear at all how this works.

Tried going through Easy to get some S ranks but keep messing up as don't have time to play through again.

If it helps any, you can skip through most of the content in each episode by pressing select a bunch. Since some of the episodes don't even have full fighting sequences (I think, though I may be mistaken), that leaves just a handful of QTEs to go through. Should only take a few minutes to get through an episode if you skip through everything it'll allow you to skip.

Tried that but kept missing a few of the syncs and getting A's as patience has rolled thin,

What a stupid idea. Capcom have lost my money I think as can't be bothered will try another hour shot tomorrow see if i can do it, but if not I'm out

I got six S ranks without even intending to do it. It just happened naturally during my playthrough. It's pretty easy.

I played on hard so struggled.

Keep doing alternate type of combos, like jump and hit. You going to get A time and S in the rest.
