Dungeon Keeper: The Deeper Dungeons Tips:
      It's almost impossible to write a complete strategy guide for Deeper Dungeons: every
      level is a stand-alone situation, and with every little error, like digging in the wrong
      direction, you will meet powerful enemy creatures that literally will cut your minions to
      pieces. Some quick advice:

      1) Train your creatures as soon as possible. A level 5 Spider can easily defeat a level 1
      Dragon.
      2) Save often; and save always before digging in a new direction, because every corner of
      Deeper Dungeons is full of parties of heroes with only two things in mind: you, and your
      painful demise.
      3) Build rooms logically. For example, Training rooms near enemy positions, Treasure
      rooms far from them, and Library far away from everything else (Warlocks don't like
      anybody else)
      4) If you notice a strange looking rock formation, with the shape of a regular room,
      beware! Almost invariably, it will be full of enemy Heroes.
