Terrain Quest

Terrain Quest is a map-based adventure. It uses a combination of simple top-down maps and look-up codes which take you through the adventure. The look-up codes are randomised, so you don't know what will happen next until you get to that point in the adventure. In this way it's similar to a gamebook. The PDF has two pages of rules, 9 map pages, and 39 look-up entries for the story, items, enemies, etc.
