Chapter 6 - Part 1 was just released. If you want it right now, it will cost you $10. If you wait 1 week, it will go down to $5. One more week, it will be $2. Then, 1 more week, it will be free.
It has only the first part of chapter 6, so, if you don't want to play a partial chapter, just don't download it.
Cheers!
