Hey Frankie, Is the crater in the Halo 3 trailer a natural crater, or ground zero of where the city used to stand? If it is a natural crater, does the crater exist in real life? Because there are crater nature reserves that are on the outskirts of Mt. Kilimanjaro. If you can't answer this because it would give something away about Halo 3, I can understand. I just want to know if it's based off a real place.
