ahh so that's why you can fix the VTOL power systems. The rover gradually loses all purpose at Astrape. Also thank you, i now know what the last persistent action is.
Also I really wonder what a speedrun of this game would look like when its finished, already there's so much to consider, like which facilities you even go to/finish. Like would it be faster to get the Laurion resource artifact first? or would the Astrape power artifact be enough of a time safe to offset that? (prolly not, but you see what i mean?)
One more question, are you just stranded at Astrape after Santorini explodes? theres not even an option to go to the dam?
