The roster, including kameos, was posted online (here) by Reddit user rearisen. In addition to revealing the lineup, rearisen shared footage from the Nintendo Switch version of the game. This footage indicated that the game might suffer from screen tearing issues during its cutscenes.
It’s essential to note that Mortal Kombat 1 has not been officially released yet. This means that the observed issues could very well be addressed in a day 1 patch or in subsequent updates from the developers. We can only wait and see. The game is scheduled to launch on September 14th, 2023.
