How do you open jail cell 4 and the other jail cells during the "Save Roland" mission?
I encountered this jail cell which obviously has loot behind it, but no way of interacting with the door seems to open it. I first saw it on the "Save Roland" quest, and later on "Out of Body Experience".
To open this door first climb the nearby ladder.
Next look for a spot where you can jump the rail onto some pipes. Run down those pipes towards a somewhat hidden control room.
Finally, switch off the green levers to open all locked jail cells.
