Rat's Nest
From Halopedia, the Halo wiki
John Carpenter's Prince of Dorkness is the nickname for a map that is announced in the Bungie Weekly Update: 10/12/07[1] . It will be available for download on Xbox Live Marketplace in the future.
It is said it will be the scariest map of all time. Dark, frightening and surprisingly enormous. It will includes veichles (The Mongoose was named in an update), but Bungie have also said that it will not 'need' them, possibly hinting at the use of teleporters or Man Cannons already seen in maps like Narrows.
