During 2015 I started with a couple of friends the idea of creating a fighting game, after realizing the amount of technology needed just to make proof of concept, we started doing the necessary tools for that creation during 2016. 
We have an "engine" on top of unity that works as per spec.
I´m the game the designer on that project but due to my expertise as an artist, I did some mock-ups and tests for possible pipelines. Sizes, animation logic/specs, visual development and benchmark specs.
For many reasons we had to put the project on hold.
