This arena, known as the Lost Bridge, also called Scislac Busorez, consists of a bridge with a large bluish-purple portal in the background. This is in fact a combination of the levels Pit II and The Pit III, with the portal being taken from the Ultimate Mortal Kombat 3 "Choose Your Destiny" background.
The unlockable characters, Classic Sub-Zero, Ermac and Mileena are fought in this stage as well as Human Smoke when played as. When all three characters are unlocked, this arena is unlocked in the normal stage reel as the first arena to be loaded in the game.
- In Ultimate Mortal Kombat, playing as Human Smoke forces the stage reel to use this stage in the next round/match only until the player loses and chooses another character.
- The odd name of this arena is actually an anagram of the name "Classic Sub-Zero", referencing the fact that he can be fought and unlocked here.
