I glitched out of firing range via a care package glitch and it was so awesome. We went all around the map, knived the moving targets and I even tried to get to the far away huey on a care package pathway (lots of the outside area is not solid, and you will fall to your death. I also got into the undermap via a soft spot where you could shoot people under the attack spawn in SnD.
This is possible, yet very hard to do in a public match, so I would guess it will be patched shortly.
The 53 minutes will forever be in my fileshare though :}
