What is the most disturbing thing you’ve ever seen in a game?

Silent Hill 3, one woman is throwing up an embryo and another one eats it afterwards. No joke.

Now for actual gameplay, I would have to go with Dead Space Extraction. Cutting off one's own arm in order to escape death is something you rarely do/see in a video game.

Forget disturbing that is downright disgusting
