As for a fighting game, Mortal Kombat X features an interesting, and quite complex, tory mode. In this mode, you play as if you watched a movie, which may appeal to some. Additionally, there are several QTE sequences here, thanks to which you have control over what happens during the cutscenes.
You need to keep an eye on what is going on, on the screen, because you may be required, at some point, to act and you will have to tap appropriate buttons, which will affect the behavior of your character. The only thing that you can hold against the developers is that you can completely ignore the QTE sequences, because they do not affect the storyline. Your character, if left on their own, will simply be kicked around like a rag doll and cut up and then, will stand to the main battle anyways. The story mode has been divided into 12 chapters, where you play a different character in each. Also, there are several opponents to defeat, in each of the chapters.
