Below Level Seven

1. I suppose you've tried the elevator as well as the ladder leading down from Level Seven.
2. Since the normal methods don't work, don't worry about it for now. Hopefully, something will open up. Meanwhile, work on other goals.
3. Don't go on unless you've found the key.
4. Don't go on unless you've blown up the storage bin.
5. Have you read the Dome description carefully since the storage bin explosion?
6. The air shaft grating is loose! Try to open it.
7. You can now enter the air shaft, and climb down to the lowest levels.
