Unsolved Maze & Snakeheaded folk
The Unsolved Maze is a module for GM created for use with The Black Hack (you must have the latest version to play this adventure). The maze is detailed by maps¸ littered with traps and inhabited by new monsters¸ so you can organize a good hunt in an underground environment. You can choose how to play the adventure (a rush towards the goal or a more in-depth exploration) and it's easy to adjust the difficulty to your party level. So you are ready to meet the Snakeheaded folk and try to discover what are they doing in their new labyrintic lair.
