| Bug, plus you must push it
There's the bug that you can usually fix by reloading, but there's also another problem. When I first played the game I couldn't get past that door. The reason being that it's the first door that can't just be opened by using the "activate" button (default "E" key). You must push the bar physically first, then open the door. Also, if there are guards after you, it'll be tough. And they keep coming. It's annoying to say the least. |
