The Mortal Kombat series has always been [in]famous for its shocking brutality, but the next game in the franchise, Mortal Kombat X, takes things to a level that horrifies even Super Bowl all-stars.  Marshawn Lynch and Rob Gronkowski join Conan O'Brien for the latest Clueless Gamer segment of Conan in which the two tough guys and the talk show host sit down to play the in-development Kombat and react to the violence.  I found it interesting that two athletes who have found success by being professional tough guys were aghast at the new Fatalities and would rather be playing Mario Kart instead.  In fact, neither athlete seemed to know much about the cast of Kombat, but they knew their Mario Kart characters and mechanics.  Seeing them reject the hardcore gore of Kombat in favor of racing as Toad and Bowser made me smile.  Mortal Kombat X is due out in April for the Sony PlayStation 4, Microsoft Xbox One, PlayStation 3, Xbox 360, and PC.
