Undercover agent (JCS)

Brian was a mole planted by the Militaires Sans Frontieres onto Camp Omega sometime during 1975. At some point, the MSF commander Big Boss infiltrated Camp Omega to retrieve Brian as well as a casette tape that contained vital information. Because the risk of having a regular chat compromising them both to the enemy was too great, Big Boss had to utilize force on him and interrogate him to ensure their covers remained intact. Brian then explained that he didn't have the cassette tape on him due to being watched, but he did place it in a safe spot. He also inferred that someone wasn't actually a CIA agent, but interrupted himself and told Big Boss good luck, as well as to quickly knock him out to ensure their cover was intact.

Behind the scenes
Brian was a character who appeared in the TGS Daytime demo as a key element to the demo. His name was supplied by Kojima, due to his being a motion-captured image from a Kojima Production staff member named Brian via the Fox Engine. Kazastayloc implied that while the overall premise will be in the game, Brian himself might not be in the final version, as he was specifically planted for TGS.
