So, i started playing the game blind, followed the goals etc... than when arriving at the factory, i was looking through the options in the computer and inadvertently chose the shutdown ending, thinking there would be a confirmation screen or something. i didn't think much of it, and i continued playing in that save afterwards, found the recovery disc and managed to find out it was used to restart the npcs. so i went and did the restore ending since i had no choice anyways, i went to talk to MK thinking he would have dialogue and indeed he had, giving me a new goal that was instantly completed, and now the factory is closed for good and i can't seem to find a way to go back in for the reboot ending? do i have to start a new save all over just to get the last ending because i'm a dumbass?
