Mortal Kombat X is coming to iOS and Android next month as a free-to-play fighting/card-game, shades of the mobile version of Injustice: Gods Among Us. The mobile MK will link to the console version for unlockable goodness. I don't know about you, but "Swipe! Finish Him" doesn't have quite the same ring.
Ah!!! Flashbacks of spending hours playing the Injustice game just so I could unlock a Batman Beyond skins are rushing back. The really shitty thing is, once I deleted the game from my phone my progress was removed and even though I linked by WBID to the game, the costume was deleted from my copy of Injustice as were the other ones I unlocked via phone. Even worse there was no DLC option...ugh this was a scar I'd never thought would reopen.
