Mortal Kombat X has been available on PC, PlayStation 4, and Xbox One for well over a month now. The game was delayed for last-gen consoles some time ago, and now may have been pushed back once again.
Mortal Kombat X for the Xbox 360 and PlayStation 3 was planned to release this summer, but may have been pushed back. Retailers such as Amazon and Gamestop now list the title at December 31, 2015, originally having the game dated for June. However, retailers such as Walmart and Target still have Mortal Kombat X listed for release next month.
Kotaku, however, reports that Gamestop has informed costumers that the game has been delayed until this fall.
Mortal Kombat X is available on PC, Xbox One, and PlayStation 4. High Voltage Software is handling the Xbox 360 and PlayStation 3 versions of the game, and had originally ported the game over to PC. The second DLC character for the game, Tanya, is set to release in early June.
