You could have shown off some really spectacularly brutal gaming deaths, but you didn't include any non-mainstream game from more than a couple years ago.
Deaths more brutal than what we saw in the video:
-Heather Mason is hit by a train, complete with screaming and ripping sounds. She can be dragged off a bridge by a large squid-like monster, letting loose some of the most insanely terrifying screams I've ever heard before being pulled to bits. And the antagonist eats an infected pus-covered fetus, stumbles into the corner while gasping, is yanked through the floor and gives birth so hard that it kills her instantly. (Silent Hill 3)
-One of the main deaths Henry Townsend witnesses is a woman beaten so badly that her blood literally covers the office she's in, and she dies begging to wake up from the nightmare (also holds number one spot for "Fastest Tear-Jerker In Gaming"). Another guy is shocked to death, electric-chair style, and the scene is so over-the-top painful that I actually slid out of my chair. You even see his cooked corpse after he dies. (Silent Hill 4)
-A small child gets his entire body bitten off, his entire body skewered by a giant spider leg, and pulled apart complete with intestines. (LIMBO)
-Everything from Waxworks. EVERYTHING.
-A woman runs at the player, screaming and crying in terror as she attacks because she's been in pain and acting against her will ever since she was infected a while ago. She gets her skull caved in for the effort. (System Shock 2)
-A dwarf is skewered by a sword, gets his ear bitten off, gets a leg knocked clean off by a warhammer then flung against a wall so hard that the other leg and an arm break clean off, is peppered with arrows, and breaths a gas that rots his nervous system and eats his eyes out. He's then taken to an infirmary with his intestines trailing behind him, has a novice diagnostician diagnose his six different fatal infections as "rotted lungs" and they perform lung removal surgery before he finally dies. (Dwarf Fortress is a royally screwed up game.)
