I am stuck on level Nova Prospekt.
I am trying to open a door but it will not open. I have got up to the part where you unplug the creature that is being tortured and so opened the barrier and i have gone into the room that has a lever to open the door to get upstairs. I have gone upstairs and and gone into the control room and i have pressed the button that should open the door downstairs so i can continue the game. My problem is when i press the button for the door downstairs it turns green for a second then goes back to red then my game auto saves and the door is still closed and i am unable to open it as the button to open the gate does not work any more. Is there another way to get passed this door as i am now stuck and getting very frustrated with the game
