What's this game about? Looks interesting.
All I've gotten into in Penumbra: Overture (the first one) is your guy finds out that his father that abandoned him when he was born died 30 years ago and left him some stuff that pointed him to northern Greenland. Long story short, you go there, nearly die of hypothermia until you find a mysterious hatch in the middle of nowhere, Greenland. You go inside to find an abandoned mine/WW2 base and get trapped inside. It's now inhabited by pant-stufftingly scary stuff, though.
The cool thing about the game though is that besides the opening monologue and things your character says when you're walking around in the mine (text that comes up on the side of the screen, stuff like "I can feel my heart beating in my chest, I've never been so scared...") you discover the story completely through his eyes and through the stuff that you look for and find. It's the kind of thing where it turns from something very small into a very intricate, very scary storyline that unfolds before/through your eyes.
