3rd episode: underground

[edmalikin]

Hello, my name is Eduard. I am playing the demo of Penumbra: Overture. After of phase II (losing the health because of getting overcold - ) I successfully find the shelter - I'm in the dark room full of barrels that can be moved but not reversed). There is a door that the game says it's stuck. I've tried to open it with variety of tools: hummer, barrel and large and long plank - neither of them worked on that door. Also I tried to put a plank on the door and go over it to get past the door. What I'm supposed to do with the door, because I think I have to open it some way.

Thanks in advance,
Eduard.
