You must click Single Player Maps and click on the space bar to see the Map! If you don't do this its not gonna work! (This is the same with the other Coop maps as well)
The map was made by Bungie. (www.bungie.com)
THE GAME DOES NOT END! You must drop out of the game to get back to bungie.net. Hopefully in 1.1 version it will end.
