2. Dead Space (Series)
If you're looking for ultraviolent games, it's hard to top a franchise whose gameplay centers around a concept called "strategic dismemberment". Oddly enough, though, it's not all the flying necromorph limbs that put the franchise squarely into bloodbath territory. Instead, it's the myriad gruesome ways that the hero, Isaac Clarke, can meet his untimely end: decapitated, ripped in half, crushed, choked, impaled – and believe me, the list just goes on from there.
Even when Clarke isn't getting brutally killed, he's getting brutally tortured or watching other characters getting brutally tortured and then killed. At one point in the second game, Isaac is even stabbed in the eye by a syringe while fully awake. It doesn't get much worse than that.
Mr. Clarke, this first place finish is dedicated to you. May you always rest in pieces.
