What is video games’ problem with sniper women?

They can’t just be competent combatant ladies who shoot stuff (like male snipers in media always are), there needs to be some “sexy” gimmick to them, apparently. Like navel-deep cleavage and brainwash, breathing through skin or, now… being helpless schoolgirls with clothing damage and panty shots galore? 



(And no, no available info suggests it’s an erotic/porn game)

The game itself looks dreadfully dull. And since only footage I could find of it seems to be sponsored by the publisher, it’s safe to say that sex doesn’t really sell, otherwise this would have had fans.
