It looks like they shot some of their scenes in the same location they did the ODST trailer.

@rouken: OK, THAT was much better than the standard version!

@PACKFAN4LIFE: Wrong. Everyone on Noble Team, including the guy you're playing, except for one is a Spartan-III.

This one is second to the ODST trailer in terms of awsome. But aside from the cool Pelican-scenes and how Carter matures, it just doesnt have the same "wow" factor the ODST trailer did.
