Penumbra is a first person horror adventure focusing on story, immersion and puzzle solving. Violence and combat is hardly an option - the player has to use wits to guide Philip through his final test, and this makes the series unique in offering a truly dangerous and terrifying experience.
Great first-persom horror/puzzle game. I played it with a buddy a whole night straight, we helped eachother with the puzzles and it wouldn't make you go crazy from the horror. Next time I will play through it alone to see how that feels like. The puzzles are really hard and they have really succeeded with the horror environements, it's crazy scary at some points. Sadly you can get immune to the horror by just being brave enough to challenge it, but it doesn't mean the game will stop being fun.
