The Munitions Plant is the first map in the Fourth Unit of Ground Zero. It is the place where the Strogg's ammunition is produced and there are numerous ammo crates throughout the facility (some of them are destructible).
The most important equipment in this area is the machine that produces antimatter cores. Once a core has been created, the player will have to provide a containment pod for it, so that an Antimatter Bomb can be assembled.
