dm_metalbox by Sir Charles Babbage, Inventor. 
Released 7/31/05.

dm_metalbox is a killbox-inspired map thats split into two hemispheres -- a Combine side, and a Rebel side.
There are tons of catwalks to fight like hell on, lots of hiding places, comping places, and sniper nests.
This map can reasonably accomodate up to 20 players. Anything more, and it gets a little crowded. :)

There is one hidden area in this map. Hint: Shoot the Breen in the throat. :)
