I have an ATI HD graphics card and the graphics are really strange in Penumbra: Overture
Get the latest update for Penumbra: Overture to fix the problem.

I have downloaded the game(as a .DMG file) and when I try to mount the image I get an error!
It seems that for some users the computer tries to be smart and adds a ".gz" extension to the downloaded file, make sure you remove it so that the file name ends with .dmg. If you can't see file extensions, go to the Finder menu, select Preferences... and under Advanced, check Show all file extensions.

I want to play the game in German, French or any other language not English.
Sorry, we only offer the game in English. It is possible to translate the game into another language, check the Modification Forum for details if you are interested in doing a user translation.
