Myst 4: Revelation Cheats - Xbox
Hints
Fireplace-puzzle in parents' bedroom
There is an incomplete "chessboard" in the fireplace-elevator, which takes you down to the two books. Number the fields on the incomplete "chessboard", starting at the bottom far left corner, going left to right: 1 to 8. Then for the next row: 9 to 16, and continue the pattern with 48 in the top far right corner. Note: Try pressing: 9-34-6-16-30-19-20.
Serenia
Serenia is, graphically, the most incredible aspect of this game. Create a save point in Atrus' Library. You will want to visit and re-visit Serenia. Earth, Air, Fire and Water, and you will be a different Child if you keep going through. The best part is where you finally get into Dream. Note: To Harmonize The Ancestors, ask yourself where do all colors begin? Note: In order to get to a new version of Serenia, you must restart the game. It is easy enough to take shortcuts through Haven. You must at least go through Haven, then Link back.
Spire: The Spider Chair: Getting all four crystals to vibrate at once
This is a very difficult puzzle. It, like the Mangree puzzle in Haven, is set up with a clock ticking. Once you have figured out which combination on the three cables makes each crystal begin its vibration time it is a matter of time. When you know those, watch each crystal carefully and see how long it takes for its vibrations to stop. Four codes, four crystals, and three cables with twelve markings apiece on them. Start the longest-vibrating crystal first. This will give you approximately 45 seconds to set off the others. Longest to shortest is the key. The main problem is keeping track of where to set the sliders on the markers without making a mistake. You can try marking the screen with something that will erase easily to keep track.
Tomahna: Bug cage
While in Tomahna at the beginning of the game, do not open the glass cage containing the bugs unless you want Yeesha to get angry with you for ruining her experiment.
Backup Power Box that Yeesha points out
Make sure you have shut off everything in the Waterfall room before pushing the buttons at the Power Box. Click combinations until both symbols for the Waterfall are green. Then, go back and open the floodgate. Watch your head.
