Labyrinth Lord
Labyrinth Lord is a faithful retroclone of 1981 Moldvay Basic/Cook Expert D&D, preserving the classic B/X experience. Seven classic classes include clerics casting at first level, with progression extended to 20th level. THAC0 combat and race-class combinations ensure compatibility with decades of OSR modules for nostalgic dungeon crawls.

Labyrinth Lord embraces the classic fantasy tropes of early Dungeons & Dragons—a world of dangerous dungeons, untamed wilderness, and ancient treasures waiting to be discovered. The game deliberately avoids prescribing a specific setting, instead providing the tools for referees to create their own worlds of swords and sorcery.
Theme and Setting
The implicit setting draws from pulp fantasy traditions: human civilization exists as points of light amid vast darkness, magic is mysterious and dangerous, and mortal heroes confront terrors beyond their understanding for gold and glory. The game's tone encourages exploration, resource management, and cautious engagement with the unknown.
How Play Feels
Death is frequent and often sudden, creating a playstyle where cleverness and careful planning matter more than character optimization. This is fantasy roleplaying at its most elemental—no metaplots, no canonical settings, just the shared imagination of players building legends one deadly corridor at a time.
What Makes It Distinct
Labyrinth Lord reproduces the Moldvay Basic/Cook Expert rules with surgical precision while addressing minor inconsistencies. Character creation follows the familiar roll-3d6-in-order method, producing seven core classes: cleric, dwarf, elf, fighter, halfling, magic-user, and thief.
