I love Overwatch, Its a video game that was released on May 2016 for Windows, PlayStation 4, and Xbox One in case you didnt know. 
That's cool! How is it played?
Well basically the game assigns players into two teams of six, with each of the players selecting from over 20 characters, known as "heroes", each with a unique style of play, whose roles are divided into four general categories: Offense, Defense, Tank, and Support.
