What do you hope to see and not see in SOMA?

[Slanderous]

Exterior Space Walk section. This is usually regarded as a cool thing fit more for an action game, but I believe that if done right it could be downright terrifying. Imagine your character getting out of the airlock, only his breath audilable, and as you carefully try to reach the next hatch something knocks you away from the station and you see the space station getting farther and farther, absolute nothingness around you.

Isn't the game set underwater?
