Demo

[gamgam2]

This is the official demo, not the tech demo.
The tech demo is the frictional team's orignal game, it was just something to show off how the engine works and what it can do. But they didn't expect it to get so many downloads. So they decided to create an actual commercial game, penumbra-overture.

The demo is the very beginning of the penumbra-overture (The commercial game which will be for around $20-25 us dollars)
But it's basicly the very beginning of the actual game, it makes you want more, and doens't really spoil anything.
Recommend you trying it=)
