My problem is that i'm stuck at D6. I just arrived in a subway cart, and I follow Miller or whoever across the other subway cars and up the stairs to the control room...but when he tells me to go up the stairs, I can't, because they're behind a closed door. All I can do is jump, crouch, run, (sort of..) and turn on/off my flashlight.
I've tried loading last save and dying but it doesn't change. Has anyone else experienced this? Or know how i can solve it?
Any and all relevant help is greatly appreciated.
