Hi there. I was not sure how to begin and where to search so just wanted to ask here about one thing.
As I am making some elctronic music since 2004 and experimenting with new themes all the time I managed to mix some vocals (character voices) from Overwatch game into one single track and make something special for listening purposes only (not sharing and fully understand copyrights topic so track is currently only existing on my hard disk and private).
However may I ask you if there is actually an option to share it public so anyone interested in game can hear it and not breaking law by any chances? It was made just for fun. 
I think it is a simple question yet did not know where to ask so sorry in advance for causing any possible troubles. Hope to get reply anyway. Greetings.
