"What is the current state of the Early Access version?
“The game currently has 4 facilities, with some information on the next 2.”
From playing the latest version, Talos, Lar, San, Ast are playable; in the latest build Str, Hip, Pne are referenced in logs etc (three, so might have been a bit after the Steam FAQ was written). I'm definitely curious to see which of these are coming next. One of those three requires a different vehicle though, so I get the feeling that one will be last.
