The newest Mortal Kombat 1 trailer highlights the games revamped version of Sektor, giving players a look at her Fatality and role in the upcoming Khaos Reigns story expansion. Almost a year after Mortal Kombat 1 launched, NetherRealm is releasing the games first story-based DLC expansion on September 24. Building off the brief cliffhanger teaser at the end of the base Mortal Kombat 1 story campaign, Khaos Reigns will see an alternate reality version of Havok raise a multiversal army to spread destruction and anarchy through Liu Kangs rebooted universe.
