Maps in Dungeon Master are the 'brain' of the game. You define a map using the construction set's map editor, shown here. By simply moving the cursor and placing walls in this 2-D editor, your 3-D world is instantly created. Special events placed on the map drive the game's experience, causing events to happen as players move around and perform actions. The game designer can also change the texture of the walls by choosing a wall-type from the wall database.
