No, each chapter is separate, if you want to play chapter 1, just download that. If you want to play whole game then you need all 3 chapters.do i have to download chapter 1 and then 2 and then all 3 parts of chapter 3? that's like over 10gb? is that how big this game is?
The Chapter 3 (current 0.33 and 6.4gb) is just divided into parts so for that you need all 3 parts to extract the game. And if you want to see old videos while playing chapter 3 (from ch1 and ch2) you need Old Videos Pack
