Walkthrough
'''.

Secrets
The map contains one single secret, which is inaccessible due to a logical error in design. The sector flag 9, marking a secret sector, is placed in the "doorway" step leading up to the actual secret sector. The player will always step over the marked sector and thus the secret is never triggered.

Bugs
See above. The bug in question is well known, but no fixes are forthcoming.
