Halo has been one of the hottest video game franchises ever since the original came out on the first X Box. Late night host Conan O’Brien was lucky enough to get his hands on the upcoming sequel, Halo 5: Guardians, which isn’t set to debut until October 27. Since the game is made for multiplayer action, Conan invited the crew from HBO’s comedy Silicon Valley to take part in an epic red vs blue tournament.
