Answer: Conan O’Brien

At the beginning of Mission 6 in the smash hit video game Halo 4, you might hear two rather familiar voices in the hangar where the mission starts. Familiar, that is, if you watch late night television. There in the hangar, off to the side, are two Space Marine grunts chatting it up about unionization, boredom, and interior decoration. Two grunts are voiced by none other than late night talk show host Conan O’Brien and his frequent guest, comedian Andy Richter.
