One of the best horror/puzzle games ever is on sale at steam. You can buy 3 awesome games just for 5e! Not bad price at all

I have played demos and techdemos of penumbra long time ago, but I didn’t bought the full version. But now I got full version of every game on penumbra for very nice price.

But one of the best things that I can say about penumbra.

• Runs on every modern computer and also on older ones.
• Nice graphics
• Awesome physics engine. (Many puzzles are based on physics)
• Lots of nice puzzles
• Interesting story
• Runs on Linux/Mac/windows (But the steam version wont run on linux natively But it looks like it is possible to run this with wine.)
• Creepy game

At this price, I recommend to buy it now, as its on sale only for this weekend.
