Professional player Raymond Lussier (aka Rambo) has made a career of playing Call of Duty on some of the biggest stages in the world. Along with his team EnVyUs they placed second at the Call of Duty Championships, even if they haven't seen similar success in recent events. But to the wider community, he's known as the most intelligent professional player out there.

I had the chance to talk to Rambo about his history as a competitor, the recent team change, and how Call of Duty is a game of logic contrary to others' beliefs.
