So I entered the factory, cleared everything out, and know where the exit is thanks to utilities I lost.
One problem: there was a terminal with a locked door in front of it and it didn't have the command 'open'. I tried to do some indirect hacking but failed.
Later I destroyed it.
There seems to be no way out any more. I can't seem to break the walls around that exit whatever I do..
So yeah, this may be intended, but that would be pretty harsh :(

I don't have the seed yet, because I'm still doing my best to find some other way.
