I have also seen the super jump, mostly tho on burial mounds. there is another way to get on top of the roof in zanzibar: you first go out the right side of the base(looking towards the sea wall) you then break the first window guard closest to the door, then jump on that platform, jump onto the window guard still up, and then have you friend jump on top of you and up to the roof. if you need a demo my gamer tag is Predator Butaro.
