You have to get all the keys, break them and defeat the merchant so that you can get to Act 4. If you beat the final boss in Act 4 it unlocks the reskin for the character you used. You can change the skin while choosing the character when starting a new run.

Cool, I got it thanks, hard to figure it out without knwing, did it just randomly anyway haha.

Themain heroes donest have alt skin right, its just the bosses I guess? tyvm

The alternate skins are only for the Downfall characters (the bosses), and Champ and Automaton both do not currently have alternates.

Cool, ty. Amazing mod btw, truly looks like a proper sequel.
