Depending on where you were standing when you finished the last module, you could either spawn in the normal map, or there’s a possibility you could have gotten the secret chapter, which is the backrooms chapter. From now on I will be walking you through the backrooms section. If you spawned normally then go to the next section which will deal with that area, this section is just for the backrooms map. Il’s also good to note that there are no pictures in the backrooms map, donc si tu ne faisais pas’t get this secret map, tu es’t missing out. The only thing that you can unlock from this area is the upgraded flashlight which you can’t get normally.

Secret Module

When you are able to start moving again, keep walking down the hallway until you see a teddy bear on a table. This is when things get confusing. Go around the right side of the pole once to enter a different area. Go down the newly opened path until you find the new flashlight on the floor. Ramassez-le. Go back and this time go down the path with the green exit sign until you find a fuse on the floor. Save your game first and then pick it up. Take it back to the room where the flashlight was and a door has now appeared. Put the fuse inside a slot and go back to where the teddy bear was. Go around the right side of the pole again and grab the second fuse and take it back to the door. Go back to the teddy bear once again but this time go around the left side and walk down the hall to where we started, and go into the new room with the « 1 » à côté. In here is the final fuse. When you pick it up go around the right side of the pillar in this room and take it all the way back to the teddy bear, go around the right, and take it to the door so we can finally leave this secret module.
