Armory

The Outworld army's weapon armory. This is where the Outworld weapons are crafted; there is even lava in the background that would have been used to make the weapons. A Mortal Kombat symbol hangs in the center room. The Armory debuted in Mortal Kombat II, and subsequently appeared in Mortal Kombat Trilogy, Mortal Kombat: Tournament Edition, and Mortal Kombat: Shaolin Monks.

An updated version of this arena is featured in Mortal Kombat: Armageddon. This version of the Armory retains the lava in the background, which a player can now be knocked into as a death trap, but now also features a giant rolling rock crusher on a conveyor belt, which is used to smash ore to be melted down for weapons-making, or any player that is knocked onto it.
