Decisive battles in MK7 will show up in single player mode when two characters have the ability to drastically change or advance story line points. This match has special character intros and each potential victor will result in a different in-game cutscene at the end of battle.
These battles will also show up in Vs mode when two rivals are matched against each other. Story cutscenes will not play at the end of battle. However, the special character intros will be shown at the beginning of the match.
