This week, to celebrate both the release of Blizzard Entertainment’s highly anticipated Overwatch and the sixth season of HBO’s Game of Thrones, O’Brien is instead joined by stars Lena Headey and Peter Dinklage (Cersei and Tyrion Lannister, respectively) on the Iron Throne (which is actually a toilet) for a few rounds of robot-gorilla smashing and shiny-butted sniping, courtesy of Overwatch which hits shelves today.
