Shafted cinematic glitch

Play the Silent Cartographer on any difficulty and de-activate the Security System. Go to the place where the cartographer is held and ram a warthog through the door where there is a cutscene about it with a Zealot running out from. Make sure the Warthog is fully in the tunnel. Note: This must be done without experiencing the Shafted cinematic yet. Then turn right to the drop and drive. These are a list of strange happenings.


 * 1.(Most common) Your Warthog will still be at the same position, nothing special.
 * 2. Your Warthog and Marines (if there are any) will disappear from the cutscene. After the cutscene, look off the edge. The warthog and dead Marines should be at the bottom.
 * 3. This one requires a lot of patience. May require a Rocket Launcher.
 * Stand at the place just before the cutscene. Walk forward and kill yourself. If done correctly, everything will happen normally, except when showing the part of Master Chief walking towards the edge, he lies on the floor. And when he kicks the debris down, he will just stand there, looking straight, and the stone will fly down by itself.
