One of the biggest mysteries in Dungeon Keeper is what to sacrifice
 at the temple. Temples also make your monsters happier, can cure them
 of disease or chicken-ness. But the most fun is to drop your
 creatures into the temple waters too see what happens.
 
 Fly & Spider - Get a Warlock
 2 Beetles - Complete current manufacturing
 2 Flies - Complete current research
 Beetle & Spider - Get a Dark Mistress
 3 Spiders - Get a Bile Demon
 Ghost - All your chickens die
 Vampire - All monsters diseased
 2 Bile Demons - All monsters turn into chickens
 Horned Reaper - All monsters angry!
 Dark Mistress & Bile Demon & Troll - Get the Horned Reaper
 Imps - Sacrifice a few of these little guys and they get much cheaper
 to create! Well worth it.
 
 
 Do NOT sacrifice the undead, or chickens, unless you like making the
 gods angry. 
 
 Speaking of the Horned Reaper, he's a great fighter, but can go a bit
 bezerk at times. If he gives you too much trouble, you can pay him
 off by dropping money on him. Makes him happier (me too).
 
 SECRET LEVELS!
 
 You can find specials for access to secret worlds on the following
 levels: 8, 9, 14, 15, 17
 
 Also, there are levels that only appear during certain phases of the
 moon (such as the full moon). The program determines this by your CPU
 clock, which can be changed. So get out the almanac and start
 exploring! 
 
 SKIRMISH MODE
 
 Solved the game? Can't find a biological opponent? You can play all
 those multiplayer maps against the computer! Just go to your DOS
 prompt and start the game using '-1player' as a parameter. In the
 following example you should be in your Dungeon Keeper d C>keeper95
 -1player or
 
 C>keeper -1player
