Warthog, Inc. (Level)

Warthog, Inc. is a discovered Halo 3 Multiplayer map that was removed from the final version of the game. This map has either been scrapped or will be featured as Downloadable Content via the Xbox LIVE Marketplace in an upcoming map pack. Most believe that Warthog, Inc. is based on the armory in the Halo Arms race trailer.

However, this map may not exist and may just be fan-oriented rumor.
