A couple of costume unlocks
I’m not long into having Quiet as an available buddy in The Phantom Pain (this was announced like a year before the game came out, spoiler warning my ass), but her costume development tree in as far as I see it is: 1) covered in blood, 2) completely silver, and 3) completely gold.
I am hoping/figuring that, because those unlocks are tied to Quiet and Snake’s buddy “bond level” that it is an elaborate Goldfinger joke.
I’m not far enough into the story that I know how Quiet came to be very naked, but I have at least heard the initial in-game explanation for why she is, which definitely doesn’t live up to Kojima’s, “But once you recognize the secret reason for her exposure, you will feel ashamed of your words & deeds.” Especially because, you know, it’s still a bunch of shit he made up, however well-rationalized in-game, and because she was clearly designed to encourage cosplay and figure sales by Kojima’s own admission. Whatever whatever whatever.
Main point is that Quiet does have some late game duds if the runny mascara and stockings looks starts to bore you. There’s a Sniper Wolf cameo costume (redo the Quiet fight on Extreme) and another uniform that actually looks pretty great (you should unlock it normally, make sure to do the mine clearing side mission). It’s a very standard look, but she rocks it.
Remember, there’s a pretty great/stupid trick for dealing with Quiet.
