To me this fortress still is rather complex (I know, it’s a complex 
).
On level C1 there’s a locked door next to the stairs. I searched a lot of bodies, but that key is probably lying somewhere else.
Anyone a hint please?
If in the objectives is said find a key then there is a key. But there are many doors that show this message “Locked. Requires key”, but it is just a door that we can’t use.
So don’t look for keys if it’s not in the objectives of the mission.
