Twisted Doors is a 16-page zine for Four Against Darkness, with a complete system for random generation of the doors in a dungeon. From doors made from tied-up branches to metal doors, doors laden with magic and mechanical traps, and unusual magical doors that demand several types of tithes, doors take on a completely new light with this supplement.
This is not a complete game. A copy of the Four Against Darkness core rules is required to play.
