Note: You can do this only in multi-player matches. Go to a multi-player match at the "Crash" map. Make sure it is an Old School match. Go to the location of the helicopter crash. There is a very tall building that should be easy to identify. Climb all the way to the top of the roof. Get up onto the blue box-like "vents". Look over at the little open door where you came out of (if you went through the building, and not up the ladder). Sprint for a brief moment, then jump onto the top of that little roof object. If done properly, you should land on the roof. Jump over onto the fenced part. This is easy because the boundaries are set there, so you cannot fall off. Carefully walk up on the fence where you see a somewhat shorter building. Sprint, then jump. If done properly, you should have landed on a roof with a satellite dish. This roof has a great view over the crash and the people will have no idea where you are. This is a great spot for sniping or heavy gunning. It is probably not as useful when using SMGs.
