Warthog, Inc. (Level)

Warthog, Inc. is a multiplayer map believed to be featured in Halo 3.

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.

Discovery
It was discovered in the recent Halo 3 ViDoc that was talking about multiplayer. A video analysis has expertly spotted the text "Map: Warthog Inc. Gametype: Escort" No information about it has been provided, and it has not been seen in either leaked or official material. However judging from it's name, it's likely the level will be set in a Warthog construction facility.
