I've destroyed the communication tower, blown up the power plant and i'm at the cabin now. The map shows a little side passage from the cabin into the installation but i've tried going through there but can't. So my question is how do you get into the Military installation?
Secondly, my compass at the top right of the screen disappeared, how do i make that come back?
Thanks all

I havn't played the level in a while, but I think you have to geet on the snowmobile and go on the ice to someplace. Check the FAQ's. I'm just glad someone posted, even though I haven't been here in a while.

You have to walk across the frozen lake. Leave the cabin and come back to the gap you jumped over to get there. Before you jump it again, steer right and there you are. Good Luck.
