There is only one story mode "file" per PlayStation or Xbox profile, but if you find the going too tough (or too easy), you can exit the mode, change the difficulty, then go back in without losing progress.
The game auto-saves after every win even though it doesn't inform you, so if you need to take a break, feel free to exit through the pause menu in your next match (since you can't pause or skip cut scenes). We'll get you through it, but remember that practice makes perfect, and many fights in MK come down to good timing and, sometimes, a little bit of luck. Winning is all that matters here, but you'll frequently find yourself on the wrong end of lopsided fights. Easier difficulties make the AI opponents a bit more sloppy and less aggressive, though all moves-yours and the AI's-will retain their respective strengths. Speaking of difficulties, you can set the difficulty from the options screen of the main menu. Given that you're playing as several characters over the course of the mode, you'll need to be fairly familiar with everyone's moves: button-mashing will get you pretty far, but you'll need to really get comfortable with the characters to finish everything up, even on the easier difficulties. You'll earn tons of coins, and the story is pretty fun (in a B-movie way) to watch, giving you some meaning for the 67 fights you'll be facing.
In Story Mode, you will play through the mythology of Mortal Kombat's fiction, all the way back from an alternate and more detailed look at the original Mortal Kombat. = Chapter 1 Chapter 2 Chapter 3 Chapter 4 Chapter 5 Chapter 6 ยป
