Once Quiet is captured and imprisoned on Mother Base, she'll spend a while down in the brig, "sunbathing" in her cell without a bra on. A song will always be playing on the boombox, changing every time you visit her, and among the various 80s pop hits of the era, you just might come into contact with a classic tune from the MGS franchise itself, Cynthia Harrell's Snake Eater, the James Bond-esque opening credits song to MGS3. It's of particular note because, of course, unlike the game's other real-world songs, this one shouldn't really exist inside the game's continuity, but hey, it's not an MGS game without Hideo violently, forcefully breaking down the fourth wall, is it now?
