Would yall recommend starting a new save once it is released in case of missed scenes that locked out characters? Personally idk if i missed any but this seems like a way to make sure i dont
You could. You can skip to chapter 3, not the prelude to chapter 3 and you'll have everyone unlocked.
But once out you could skip to the prelude to chapter 3 and make sure you didn't to see all scenes in the prelude if you want. Mostly there's just set up scenes for the stuff in chapter 3 with people.
