So I downloaded this last night, and either I am retarted or something glitched in the demo but I could not for the life of me get the character to go up ladders. I tired everything I could think of even restarting and still couldnt get up the ladder at the other end of the bunker. Now I havent beaten it on the PC but I do own it and remember going up that ladder, unless there is a trigger I am forgetting about that is required to go up it, I also cant go up the same one that gets you down there in the first place.
