I was playing Perfect Dark recently and I remembered my old trick.

If you go down to that hanger/garage type place, you can find a hover box. You can grab the box and drag it all the way upstairs to the Firing Range, and jam it in the door. If you open the door to the Carrington Institute, then run through the wedged door and pick the remote controlled rocket launcher, you can fly the rockets around outside and do some glitchy things.

Anyways I just figured I'd mention this.
