Warthog, Inc. (Level)

Warthog, Inc. is a multiplayer map that was possibly 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, or was renamed.

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, but this is all only speculation.

In a recent photo of a list of multiplayer maps, it did not appear on the list, so it may have either been removed or renamed. It may also be the same map as "The Pit", since that map does indeed have a multitude of (non-usable) Warthogs.

It may also have been a forged map.

Discovery
It was discovered in Halo 3 ViDoc: Is Quisnam Protero Damno!. The text "Map: Warthog Inc. Gametype: Escort" can be seen somewhere in the video. No information about it has been provided, and it has not been seen in either leaked or official material. However judging from its name, it's likely the level will be set in a Warthog construction facility.
