Mombasa streets camera glitch

This is a glitch in the Halo 3: ODST level Mombasa Streets that lets you explore the city wherever you wish

How to do it
First, you need to start the campaign in Prepare to Drop. After the cutscene, the player will be in the drop pod. You get out of the drop pod as usual and then you are free to roam around. Exit the game whenever you like, but it has to be before going to the level Tayari Plaza.

Then, in Theater mode, you can play the film up to where the rookie gets his gun out. Using the right trigger to play frame by frame, press Y every frame until you get the free-roaming camera. Then you can go up into the area where the skyscrapers are and you can explore everything from above the Invisible Walls; the city, the skyscrapers, even the Space Elevator.

Trivia
When exploring the city from above, you can only see the sector where you landed in the pod. Everything else hasn't loaded because of game progress and loading gates to other sectors.
