Ghost Town

O.K. Corral is a Halo 3 multiplayer map.

Almost nothing is known except that it is asymmetrical and it is a small map. It had its lighting "changed considerably" to better fit the "death-at-sunset feel." The level has been describes as a bridge between nature and failed human civilization. It is reported to have many multi level, open air cat walks with sights down to semi protected alleys where you can "rain death from above".

This may be a reference to the Gunfight at the O.K. Corral, hinting the name. So it may be inferred it is in a city like map. Much like Bungie said perfect for medium and close range battles. Combining this with the fact of the catwalks, it may be a remake of the Halo 2 Multiplayer map Turf. As it featured two catwalks on 2nd stories and several alleys.
