If you don’t have a new-gen system, you are going to have to wait even longer for Mortal Kombat X . Originally slated for a summer release, Mortal Kombat X has been pushed back to sometime this fall for last-gen systems. No explanation for the delay was given, and Warner Bros. Interactive has not yet commented on the delay.
This has been a long push back from the original release date, which was supposed to be April, at the same time as every other version.
The delay may come as a result of High Voltage’s spotty work on the PC edition of Mortal Kombat X , which has been behind in patches and has had numerous bugs. High Voltage is also in charge of the PS3 and Xbox 360 versions, and likely is trying to make these versions suffer from fewer bugs.
