Mortal Kombat: Tournament Edition includes a gambling system where players can place bets on the outcome of linked battles, mini-games and other secret fighting challenges. In addition, two forms of “kurrency” will be available – red and gold – to wager with combatants. With red “koins” (new and exclusive to Mortal Kombat: Tournament Edition) players can also unlock or purchase hidden characters, backgrounds and other features in the “krypt.” New dynamic battlefield environments such as the Lost Tomb, Wu Shi Academy, Sarna Ruins, Molochs Lair, as well as other popular backgrounds from the original Mortal Kombat: Deadly Alliance have also been added.
