Trapdoor is a set of free rules for dungeon adventures. The authors write:

TRAPDOOR is a set of rules which allow players to explore perilous subterranean fantasy worlds using little more than dice, miniatures and their imaginations. It was born chiefly from two desires:

• To devise a simple dungeon adventure rules engine that still allowed for detailed character development and thus longevity.
• To create a set free from the constraints of being tied to a predetermined sword & sorcery background. In this way players can use whatever fantasy miniatures they have to hand and can place their games in whatever ‘world’ they like.

The bestiary chapter provides the profiles of numerous generic fantasy creatures – from Goblins Warriors to Fire Drakes – but gamers are also free to create their own too using a simple points system. Trapdoor is also scale-free, so whether you want to adventure using 28mm or 10mm scale miniature or anything in-between the choice is yours. Whatever divergent fantastical lands you wish to explore Trapdoor provides the tools for you to do so!

Like most conventional dungeon exploration games Trapdoor pits a single referee or ‘Games Master’ against players who control individual characters, the ‘heroes’. The hero players can choose from four races – Human, Halfling, Elf and Dwarf – and six classes: Barbarian, Cleric, Knight, Mage, Ranger and Thief. Whichever race-class combination you choose each has attendant strengths and weaknesses, but all will form an integral part of your party!

To get gamers started an introductory quest is included. Fans of classic dungeon crawl systems need look no further!
