Under Cover of Darkness is a Z-machine interactive fiction game written with Inform 6 and is © 2000 by Christopher Huang. It was an entry in the Speed-IF 9 event.

This walkthrough is provided free of charge since I wrote this walkthrough prior to January 2015 when I began my Patreon account, and also because the work it's based on has less than fifteen locations (so I wouldn't have charged for it anyway). I've since reformatted this walkthrough to use my currently preferred style. I hope you enjoy it!
I'm still creating new walkthroughs! Larger ones too! Please visit my Patreon account if you're interested in helping me create more interactive fiction walkthroughs. I appreciate all the help I can get! Thanks again.
