I hope they expand on story mode using Shang Tsung's ending. I would love for Fujin and Raiden's plan all along was to deceive Shang Tsung by allowing him to take out Kronika. Then Fujin and Raiden assemble their own suicide squad consisting of Rain, Mileena, Ermac, and Smoke or Havik. I could see Ermac being connected to that crown of souls.
