I'm wondering, how does health work in Hardcore? Because if I still need to empty 150 machine guns rounds into a super mutant's head to kill him, and anyone needs to empty a dozen clips on the player to kill him, that pretty much breaks the hardcore difficulty.
I'm thinking it should be like FEAR's difficulty: guns get more lethal, so you can kill enemies easily if you aim right (and cripple them faster) and they can kill you easily if they aim right. I hated how in FO3's endgame I was only a giant tank on legs and so were my enemies. Of course, some creatures can take a lot of punishment, like a giant armored radscorpion and I'm guessing super mutants or enemies with power armor or metal plates could take more punishment as well, maybe even have the armor plates reflect bullets so you'd have to hit them where they're not protected (think super mutant brutes with their horned metallic helmets and shoulderpads).
