I'm having problems with the artus denention level. I have entered the prison area, fought my way to the top of the building, and activated the button that freed all of the prisoners.
I then met one of the prisoners in a big hanger. He told me that we need to capture the base commander. I went back to the room with the prison controls and flicked another switch. There is one glass 'display' that I cannot shoot in this room with a picture of a fan on it. Once I hit the switch, the fan starts turning.
I've then checked all of the doors that I can get through from the hangar, but I can't find any way of getting through some of them.
So where / how do I find the commander ?
