There will be four silver pieces in the shape of bars near the opposite wall.
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.
Kill and not get hurt by Deadites
When you are killing Deadites, Zombies, etc. with your chainsaw, impale one with your it. Notice that the other deadites will not attack as you do this. Then when your impaling is over, quickly impale another Deadite, and repeat.
Defeating Eldridge
Wait until he is walking toward a barrel and gets close to it. Then, shoot the barrel and it will explode, flipping him over. Start shooting him after he flips over. Later in the fight, he will start charging you. When this happens, run along the walls until he runs into one, then start shooting him.
Defeating Nathaniel Payne
Use your shovel like a baseball bat. Hold X and release when he throws a chunk of rock at you. Do not get the rock confused with the energy ball that is thrown.
