DARQ: Complete Edition

In the first chapter, after you solve the puzzle where you have to rotate the room to make the weights on the rails slide and press the buttons (key, skull, etc), instead of going left through the newly opened door, use the closed door on the right to go up the wall and across the ceiling. Follow this path and it will lead to the journal. If for some reason the door on the right is open, you can shut it with the lever right next to it. Make sure you grab this before you take the cog from the room through the left door, as it shuts off the power and you cant close the door as needed to get onto the ceiling

If you are going back and collecting any journals you missed with chapter select, you do not have to finish the level to save it. You can immediately quit to the menu / choose a new chapter after picking it up.
