Cortana, one of gaming's most iconic AIs, appears in Halo naked to give her "the upper hand", Halo franchise director Frank O'Connor has revealed during a GamesRadar+ livestream.
"She's not really nude ... but that's what it makes you think of," explained O'Connor. "So one of the reasons she [chooses to appear without clothes] is to attract and demand attention. And she does it to put people off so that they're on their guard when talking to her and she has the upper hand in those conversations."
O'Connor continued: "It's kind of almost like the opposite of that nightmare you have where you go to school in the nude. You're terrified and embarrassed and she's kind of projecting that back out to her audience and winning intellectual points as a result."
So, you could say nudity gives Cortana a tactical advantage.
