In Shadow of colosseus, each time u have to kill a Coloss. I m not sure if these beasts feel or not ur "weapon in their head" but I know their is a lot of violence in the game.
Also when u lose ur horse.
MGS3 with The Boss
Also MGS1 with Mantis when he put away his mask
SilentHill1 when u face Lisa and when she starts "crying blood"
SilentHill2, at the end, when u access the Marie's letter.
AnotherWorld (Amiga), at the end, when u escape with ur alien ally
Time to Work !
