I was wondering too, but probably he'll upload it in the upcoming days.

No he didn't, other priorities came first probably

I guess it is hard, i'v been playing it and still haven't past Chapter 4 yet ... anyway.. Pewdiepie Has a lot on his mind but i'm sure he'll give it another go xD DONT GIVE UP ON HIM!

I don't think he has given up on this game. He just might want to play something else instead of it.

I was curious too about this, except I want to see the rest of the game. I'm really curious about the story and how it plays out, but the game itself looks lame...if that makes sense. Just overly gorey. I want the story!

I remember him saying in one of his videos that the next one, part 5, will be uploaded some time in the future. I think during that time he was visiting his family. My guess is that he's finishing the game and uploading the rest of the videos to his website. The same thing he did with Alien: Isolation. I could be wrong but I'm hoping that he didn't drop the game. I'm really looking forward to the next part.
