Aww, see… what had happen was… yea…. But now my doors are all stuck open over there with my crew, holed up in the engine room. Nothing works except my weapons which sort of work and my engine and o2.
The only way to close your doors is to repair the “doors” system (appears as a vertical equals symbol). It only has to be repaired one point to allow you to close all doors.
This will be very difficult to do in your situation as your crew may die of oxygen deprivation before they can make it to the door control and perform the necessary repairs. In this case you appear to be beyond all hope.
