This secret area with an opened supernatural vortex is called the Hidden Portal. A bridged area and ruined towers (that are in fact the "Choose Your Destiny" towers) can be seen in the background and a portal in the sky. The backdrop is actually the backdrop of the "Choose Your Destiny" screen of the original Mortal Kombat 3, with lightning striking in the center of the portal, and the bridge from the Pit III stage is provided as a walkway for the kombatants to fight on.
