Hint: Dearborn police station:
When you get to the Dearborn police station, the yard where you need to go is surrounded by Deadites. You do not have to kill any of them. First, find the Spell Scroll that allows you to posses a Deadite for a limited amount of time,.This spell takes up three mana. Posses a Deadite, then run to the other side of the yard. You will find the Cypher and a envelope that you must take to the auto body shop. Note: The police Deadites will not recognize you as Ash, but the others will.
Hint: Finding the crystals at the museum:
First, get a device that beeps when you are near a crystal. To do this, go to the picture of Nathaniel Payne and place the two pots you found in the basement there. The picture will open and you will get it. The first crystal is in the small Civil War section near the guard. Blow open one of the houses. The second crystal is under one of the ice age animals. It is the one up in a cave. The third crystal is in the center of the sun diagram. The final crystal is in the corner of the Egyptian section. This last crystal has a map behind it with a symbol by each section. Remember the symbols because they represent the order that the crystals go into the wall.
Hint: Crystal order at the museum:
The order to insert the crystals is red, yellow, blue, green.
