Also do you know how to get all the secret achievements?
Viewing post in I know this game hasnt been updated since August, BUT!
I certainly do. Each of the hidden achievements correspond to an ending. The stickied walkthrough explains how to achieve each ending. The ones that don't have a specific explanation involving finding a scene with some prerequisite. I can answer questions about any that are giving you trouble. Or maybe I should make a guide for achievement hunting as well. What do you think?
