Neptune:

Follow the link which best matches your desired question:

I've pulled the lever and walked into the shed thing, but there's nothing in there, what now?

How do I get across the drawbridge thingy?

I've climbed down the hole in the ground, but how do I open the door down there?

How do I start the motor thing?

I don't understand this Neptune bomb, how do I disarm it?

What does the number that comes up (when I disarm the bomb) mean (MAJOR CHEAT WARNING!)

Where can I get an overall map of the planet Neptune?
