Well this was a surprise. We got a surprise teaser trailer today for Mortal Kombat 11 and teases the future of the game as it seems a trailer for a Season 2 of DLC is on its way.
It appears also that we may be getting DLC for the story mode, which would be the first time NetherRealm has done so with their games. In the trailer we Raiden and Liu Kang from the ending of story mode before they are interrupted by Shang Tsung as Shang and two other shadowy figures emerge from a portal.
The teaser ends by saying the full reveal will happen tomorrow.
