Secret Location: The Hall of the People: This game was designed before Cyragon existed, at that time our name was Mug Software. So, enjoy our Hall of the People - a location that gives a behind-the-scenes look at the Mug Software team.

Accessing it is tricky; it is extremely unlikely that you will find it while going through the game. Here is how you can visit it:

1) Go to the Desert Rimworld Power Plant
2)Go to the small panel beside the door that leads back to the surface of the planet. It's the panel where you can enter a coordinate and go either to the surface or to another part of the power plant.
3) Instead of entering a coordinate, type: Hall of the People Once that is entered and the button is pressed, the next time you walk through the door you will appear somewhere else entirely...

Secret Location: The Secret Room: This location was added near the very end of the game, while working on Part III. You might be able to find this on your own but it's tricky. Here is how you can find it:

1) Go to the Underground Labs
2) Walk over to the fusion reactor testing center (the room with two fusion reactors, one of which is dead) but don't go inside the room. At the end of that hallway, just past the doorway that allows you to enter into that room, is a set of glowing field bars that seem to be barring the way.
3) Walk all the way up to the bars; you'll see that you can't go forward. Turn once to the right (or to the left - it doesn't matter), turn back to face the glowing bars, and try to go forward again. The way will still be barred.
4) However: if you try this 7 times, on the 8th time it will let you through... into the Secret Room.

There is a secret inside the Secret Room - the only hidden non-obvious hotspot in the entire game. One of the walls is hiding something, but you can find it if you turn on the option that makes hotspots visible.

The Global System Password: In the Vault hidden away on the Valley of Stars there is a small journal. Part of the journal says this: I have a vague memory that there was some sort of global password, named after a ficticious inventor (a Quick somebody, or maybe it was Fast) but that was so long ago that I have only vague memories of it. This is actually a hint; as far as I know no one ever picked up on it. When I was building The Key it was necessary to solve certain puzzles over and over again, and to make it easier I built the puzzles so that there were two solutions: the correct one, and a single phrase that worked everywhere and would unlock anything. This made it easy for me to test out a location without having to constantly look up passwords.

The global system password, then, is real. It is: tom swift. Tom Swift was the main character in four different series of young adult science fiction books. The global system password doesn't work everywhere but it does work in quite a few places.

The Graveyard Rimworld Library In the Graveyard Rimworld there is a security door that requires a password before access to the library will be granted. The password is one of a great many cryptic, obscure references that I placed inside The Key; it refers to the Dig Allen series written by Joseph Greene (one of the first science fiction series I ever read). There are far too many references to site, and many of them are very obscure; those who appreciate them will find them.

However, the door guarding the way to the Graveyard Rimworld library actually responds to more than just that one phrase. The complete listing is:

• tom swift
• ned newton
• mr damon
• commander keen
• captain keen
• mortimer mcmire
• xyzzy

Some of those will open the door and some won't, but they will all cause the game to do something interesting.
