I also once played SS13 and they kept changing the secret adventure zones every few months, so that you couldn't learn them unless you were connected to the dev team. They were really hard to get to in the first place, unlikely to happen before the round ended and if it didn't end yet then it was about to, and with the role-playing rules you had to have a good reason to be there or you'd be banned for meta-gaming. Mostly that meant you got lost in space, or someone threw you into space and you managed to survive, or you were a teleporter scientist, or you were a bad guy who found them in a previous round (allowed meta-knowledge) and trying to raid the area for supplies. Those were about the only ways to end up in secret areas.
