You're going to start facing a wall turn towards your left so that you can see a hallway take a step forward into the hallway so you're right next to this old AC thingy. Take one more step forward so you're kind of in between the two opened doors. Turn towards your left so that you can see one of the opened doors step into the room. Turn all the way around so that you can see the other door. Step into that other room so that you're at... and once you step in there you should see... a red table and you should be standing on top of the red colored rug thing. You're going to turn towards your left and if you see that weirdly opened door, not the one we just came out of but the other one walk towards it and then... If you're still looking forward at the end of the room you're going to see a giant cross. Walk towards so that you're standing right in front of the cross. This will be your finishing point.
