The new Halo 2 maps Tombstone and Desolation have been released for like, what, 30 hours and are already being torn apart. Over at Halo.bungie.org the legendary Mr. Wu posted a bunch of links cataloging all the glitches and easter eggs surrounding the two new maps, including an original Halo pistol sighting. And yes, you can pick it up via modding. People have even found a way to get out of the map in Tombstone, avoiding the instant kill barriers that float above head. Poor new Halo 2 maps ... you didn't even stand a chance.
