Amid rumors of a potential MK Trilogy Remaster, we have an opportunity to see how those games would look in action. Initially reported by DSO Gaming, the demo from the canceled fan project is available online for download.
It appears pretty barebones, the Unity version (one I messed with) just gives you Sub-Zero and red Sub-Zero. The Gamemaker one lets you mess with Scorpion as well. It's nothing super crazy, but it's a fun way to fill a few minutes and it lets you live out the fantasy of playing this game that never was. You can get the Unity download and Gamemaker download in the respective links attached. Below, I'm attaching a video from Interloko, who tagged us in a stream he just finished which got me to discover this. It appears as if he's playing a newer build/different fan project, but looks great either way.
