Penumbra: Overture (PC/Mac/Linux, 2007)
We love a good scare in our video games, and Penumbra doesn't disappoint. The series, which began in 2007 with this title, is developed by Frictional Games, a small indie development house based in Sweden that specializes in games of the pants-wetting variety. The series follows Philip, a physicist who receives a strange missive from his once-presumed dead father. Tracking down the origin of the letter, he finds himself trapped in an abandoned mine in Greenland full of juiced-up spiders and rabid canines. Not exactly the European vacation he was hoping for.
