You gotta hit these rocks at Valhalla just right to get into the base. Bungie.net now have a 'Beta' facility where players can convert their file share material to WMV files. This makes for easy web posting, and now everybody can show off their skills like this. I'm trying the rocks and the base at the other end of the map now !;) This was successfully landed during a matchmaking slayer game! some guy had quit so the game turned into a skip pan. (less info)
