There is Sargent Marks Brutal Doom
Now enemies can be dismembered, scream in pain, shout profanities, everyone can be ripped apart (including you), basic enemies have assault rifles instead of pistols (and you have to pull the charging rod/prime your weapon). The gore is detailed, the enemies have more actions to suit their aggression, nearly dead enemies will pull themselves up just to fire more shots at you.
CoD might as well mean Canadians on Duty. They fall over so nicely when shot, they might as well just say sorry. Mario Bros is arguably more violent.
Real war has so much screaming, panicking, nobody can smell through all the lead and iron. Starving in the blazing heat, with a machine that feels like a pickaxe on your shoulder, but you don’t care, because your head is going to randomly disappear. Nobody can hear shit, unless it’s an explosion, or a full grown man shouting at the top of his lungs, you have to lurch in holes, hide against walls, and for once in your life a cigarette is the safest thing you can do, until the tiny ember alerts a carbineer or sniper. They pack some Skittles in your meal to remind you of home, but you’re far from home.
Rifles go through several inches of muscle if not straight through. they shatter bones, melt soft tissue organs, put an expanding gas cloud in your body, and the pressure wave damages your nervous system. People painlessly dropping to the floor is something that rarely happens, but that’s what Hollywood sells.
Speakers can’t even reproduce the sound of a gunshot. If they did, everyone would be deaf and sick to their stomach.
