How is Shang Tsung still alive? Is Ermac's ending in MK 10 some form of canon? Or is this part of this weird time storyline where characters from the past, whether they are dead or not are brought into the current time?
Are you getting it for Switch or...? If Switch, you'll probably need an SD card. the game is gonna have a day 1 patch that's 15.9GB. so check your Switch to see how much space it has if you're getting it on that.
