In Dark Passages, your goal is to travel down, through level after level of evil creatures to reach the final goal of defeating the Dark Lords and stopping their invasion. You do this by finding the exit on each level and descending deeper into the Underdark. On each level, also, there may be Lock Hexes. These are impassable blocks or doors with a symbol on them. Find a maching symbol somewhere in the dungeon and break its shape to open the Lock and continue on. At the end of each area, there will be a Guardian. The Guardian must be defeated in single combat in order for you to leave that area.
