When Conan O'Brien and his sidekick Andy Richter visited 343 Studios and joked about recording dialogue for Halo 4, we had this faint hope that they weren't actually joking. And lo and behold—what should we find in the "Shutdown" mission but the red devil and Richter themselves?

We were delighted to encounter the show-hosting duo, even if the dialogue sounded familiar. Just look around in one of the early areas with lots of marines in it.
