Bit Tech just published an article covering some of the brightest games from this year's Independent Games Festival:
"One of the more accomplished titles to be spotted on the list is the first episode in the new series from Frictional Games, titled Penumbra: Overture. In order to quell any nay-sayers we’ve been in contact with Frictional Games a bit over the last few months and we can promise both that the second episode is on its way and that we’ll be getting a good look at it when it does arrive.
Penumbra began as one of the most popular and most downloaded indie games ever and the original game was a short, self-contained tech demo which can be downloaded here if you want to get a taste for the full game.
The game is the first part of a continuing series which tells the story of Philip, a physicist who gets a mysterious letter from his long-absent and supposedly dead father. Philip sets out to investigate and predictably enough gets embroiled in a survival horror situation in an abandoned bunker somewhere in snow-swept Greenland."
