Those of us who have played the game for a while will be aware that there is lore attached to the abandoned buildings. A sub-plot, that is released in small instalments with each new building you visit. The story plays out in a specific order over 20 - 30 visits (I haven’t counted them). When you get to the end, if you keep on visiting abandoned buildings, the story starts again.
What I wasn’t aware of until recently (I think it’s new), is that there is now similar lore attached to the manufacturing facilities / operations centres - the ones where you have to blow the steel doors off. But it’s by no means so obvious.
When you visit these factory buildings, you will usually be given a little task or puzzle to solve. If you complete the task correctly, you get a reward, and some of them are extremely valuable. They are, for instance, where I got my 18 million plus blueprints. I suspect most long-term players are aware of this, too.
What you may not know is that the tasks and puzzles in these buildings also come in a predetermined sequence, and there are a limited number of them (again, around 20 - 30 I think). Once you have completed all the tasks, the buildings stop giving you rewards, and start giving you lore, instead. There isn’t a lot - perhaps 6 or 8 snippets of story, but it’s fascinating.
For instance, I’ve long suspected that the Explorer ships were made by the Korvax. Well, they are. And not only that, they have minds - intelligences just like the Korvax bodies. Here’s that one as a taster:
Good luck hunting that story.
