Ok this one is my personal favorite and i still havent mastered it, but its the coolest looking thing in the world. First off go to burial mounds. Then, you need to set the game options to overshields and swords, with a covenant tank in as the primary heavy v. Have the host of the game get in the tank and make its way towards the big pole that the ghost is usually found out. Have somebody move the ghost and have the tank guy shot the pole in the center for somebody to stand in. Have the person croutch walk into the center of the pole and then turn directly 180 degrees around towards the tank, then continue to walk straight back. Line the tank up with the person and have the tank accelerate into the person head on. THis should knock the person back and through the pole. Then all can look up and see the dead person's body (its about 60 times as big as a regular body)
The reason this happens is because the sky of bm is stored underneath the map. So if u can survive the fall through the pole, you will end up in the sky. Once i get home, u can all message me about how it is done.
