People have been reporting finding Portals and trying absolutely everything to get them open, but modders have checked them out and I'm pretty sure they are unimplemented like the other half of the game. Hilarious to have models of the portals appearing on the planets with no purpose, and I think they can only be found by flying low since I think they don't appear on scans, making it look like an unimplemented feature even further.
However, there is some text within the data dumps that implies that the portals were
planned to be implemented. You were to talk to a portal, and the portal will ask you a question. If you answer in a manner that makes the portal happy, you can travel right through...otherwise it closes up. For now, portals are just cut content that Hello Games made an
honest attempt to implement.
Reddit claims that Steam is now offering refunds, even if you go past the hour limit. Flying Dice, have you successfully got a refund yet?
