Also ive found a lot hidden places around school and own which you don't need download for. First one is in boys dorm, go in hallway that leads to door outside, look on your right, there will be a trashcan or something u can hide in. Go in, rotate Jimmy so he is facing the walll, and press r to get out. You will then be in another students room. You will see two beds and a dresser. If you move to far though, you will spawn back inyour room. Also when you go out of the dorm and you get to the center where on youor left is boys dorm and your right girls. Got to the right top corner of that center, there will be another bin. repeat same process, jump out while facing wall, and you will be under the school. There is also one in the girls locker room in the gym, and one in the asylum. The one in the asylum puts you in a room with a white floor, where you can see and shoot things out, but nothing can come in. Oh and one in front of Harrington house that gets you stuck in one of the pillar things.
