  1. tried doing airlock puzzle and immediately saw it was 50% broke, then I followed it halfway through and beat it in like a minute

  2. Most of the guide is perfect, except for the airlock puzzle. A lot of steps are skipped here and some are just inaccurate.

  3. I see you guys already beat me to it. The airlock part of the guide is atrocious. Definitely almost broke a controller trying to follow this “guide”. Either fix or delete I dont want any other controllers to face this anger

  4. Yeah, the guide for the airlocks is total trash and fucked me up really bad. Infinitely easier without the guide.

  5. I agree with the other two comments here.. The Transfer Line “guide” is horrible. It gives detailed directions for some parts, but then is like “go back to the third room” without any point of reference as to *what* the third room is. The entire second half of the second part is basically useless because it skips steps as well.

    If you are going to use some made up references to rooms, then it should at the very least include a map showing what those references are.

  6. It seems someone figured out the airlock portion randomly, and then tried to recreate the guide by thinking backwards, but some portions are heavily inaccurate, I’d recommend elsewhere if you need more assistance.

  7. Can you please provide pictures for the transfer line part? It’s extremely confusing when you’re simply saying “the fourth/fifth/sixth/etc.” rooms.
