Mortal Kombat 11 Friendships are comical finishers added to the game in a free update alongside May 2020's Aftermath DLC.
Originally a feature of Mortal Kombat 2 all the way back in 1993, NetherRealm has brought them back as an alternative to the various fatalities every character has.
By inputting a specific series of buttons at the end of a fight, it's possible to perform these amusing finishers which range from cuddling a giant toy bear to doing motorcycle tricks across the screen.
