Dead Space

Game Title: Dead Space
Your name: Rami Ismail
Pretty or ugly: Pretty
Description: In space, noone can hear you scream. They nailed that in this video.

At 1:16, you can hear a weapon being used quite clearly. After the player turns the room into a vacuum, as he disposes some of the enemies around 1:56, you hear the sound being extremely muffled.

This is one of those details that's often overlooked, and extremely well and atmospherically implemented into Dead Space.
