About Penumbra (overture)

[Taco]

Ive read up a little bit about the game and I was wandering is the game based on like setting up a base and living off what you can find in the game enviroment or you have to explore and dont get attacked as much as possible and go through the campaign. This game intrests me because Ive always wanted a survival where I can like set up and learn about the opponents (aliesns, zombies, etc). Sounds stupid I know, but just wondering.
