Mortal Kombat XL is a 2016 fighting game developed by QLOC for PlayStation 4, Xbox One, and PC, released as the definitive edition of Mortal Kombat X. It bundles the base game with all downloadable content characters from both Kombat Packs, along with nearly all bonus alternate costumes available at the time. Beyond serving as a content compilation, the release also introduces gameplay refinements and an overhauled netcode built around a rollback system, which improves the stability and consistency of online matches. The rollback implementation marked a notable technical upgrade for the title, addressing a common point of criticism in competitive and online play. For players seeking a complete version of Mortal Kombat X without acquiring additional content separately, this edition consolidates everything into a single package.
