That's not even remotely close to tit armor and you know it.
A man's torso is not defined by society as "sexual" in the least. Otherwise, men would be required by law to cover up at all times. And way to just handwave away ridiculous male armor as "tastes have changed", yet still get pissy when a woman points out that the boob armor trope is outdated and retarded. So men are allowed to decide when armor designs are stupid, but women aren't, huh? God, you're a faggot.
Doomguy's armor in the original Doom didn't have the abs exposed on purpose: the box art clearly shows a thinner, underlayer was torn away by a demon's claws. At no point was he designed to look sexual, give me a fucking break. Name a game where the men are sluttier-looking than the women.
