This chapter contains a complete walkthrough for Blake Against the Machine, one of the levels that is a part of Chapter 4 of Outlast II. Inside, you'll find additional tips that will help you complete the mission in a timely fashion. The walkthrough also marks the locations of occurrences and notes found in the course of the level, as well as the locations of batteries and bandages which will prove to be very useful during your journey.
The first thing you'll need to do is to push the small desk up to the opposite wall (the one with the locked door) to create a footstep that will enable you to leave the room by climbing to the ledge marked by a red rectangle. If you are in need of bandages, you can find one on the table to your left. Climb the ledge and descend using the nearby stairs. Once you're at the bottom, crouch and enter the rooms on your right. You may hear some distressing sounds, but you're safe for now.
Approach the opposite side of the room and approach the shelves to find a narrow pathway. Make your way forward until you've found yourself in the room seen on the screenshot above. Search the left side of the room to find a note (Knoth's Gospel Ch. 7. #6).
Once you've picked up the note, turn right. You'll encounter a door that has to be moved to the side. Unexpectedly, a heretic will appear behind you once you've got closer to the door. Enter the room and lock the door  behind you in order to have a moment of peace needed to find an escape route. Approach the table  found in front of you and bring it up to the ledge  which will lead you out of the building.
Get through the hole and run left. You'll be forced to jump off the wooden landing and proceed underneath its dais. Get past the stairs and keep running ahead. Make your way across a set of narrow beams. Once you've reached the other side, turn left and climb the stairs. Turn right and make your way forward.
You've managed to get to the next stage.
