Warthog, Inc. (Level)

Warthog, Inc. is a multiplayer map that was removed from the final version of Halo 3. The map has either been scrapped, will be featured as Downloadable Content via the Xbox Live Marketplace in an upcoming map pack, was renamed or deleted.

Speculation
Due to the name, and the recent trailer, Arms Race, a lot of factory materials might be in the level. This also might be a "Watch where you step" level, considering the many machines working on the Warthogs and hot molten steel pouring everywhere. This might also be a Warthog training ground, where UNSC troops practice driving and shooting. It may feature a Warthog assembly line. It is also theorized that Warthog Inc. may be an early Forge map-editor test. The map is rumored to be The Pit, since there are many warthogs stationed outside. It may also have been Foundry, because of all the industrial equipment.
