This chapter is a full walkthrough for the stage called Raining Blood found in Outlast II game. Here you can find tips that will help you to finish the stage. The recordings and documents, that must be recorded by using the camera, as well as the locations of batteries and bandages which are a crucial gameplay mechanic are also highlighted here.
The stage starts with you under the water in the pool. The demon is close so you should start swimming in the opposite direction. The best way is to follow the lines on bottom of the pool. By doing that you will quickly reach its edge. When you go out from the water the demon will disappear.
Enter the women's toilet right next to the pool. You notice that blood is pouring from one of the showers. After a while the entire floor is covered in blood. Record the shower (They're All Going To Laugh At You #12). The door to hallway are closed but you can access it by going through the man toilet.
Run in the direction of the light and go up the stairs. Right when you cross the door to the hallway the demon will appear on the left. Turn right and keep running. When you reach the door the demon disappears and Blake will find himself standing away from them. On the left you can find the opened computer room. There, on the table with the projector, you can find a battery.
Follow the direction where the demon appeared earlier. When you enter the well-lit hallway you will notice a lot of blood. You must go straight. But if you back of before the first sprinkler, take a run-up and perform a slide on the blood you will unlock a trophy/achievement - Slip and Slide. At this point nothing will chase you. This means that you can try as many times as you want until you unlock the trophy/achievement.
At the end of the hallway on the left you can find an opened room. Inside of it you find a ladder. Use it and climb up to start a new stage.
