Silent Hill

In the hospital get the plastic bottle from the kitchen. Then go to the room with the red liquid. Use the bottle to scoop up some of the liquid. Then when you have to fight Cybil use it on her when she gets close to you.

For three Heath drinks, search the wrecked Drink-machine in the first floor for health drinks.

Get to the school. When you get to the room with the piano, first press the 3rd key (White), then press the 10th key (White). Then press the 11th key (Black), then press the 8th key (White). Now press the 2nd key (Black). They should all have been dead keys. The Silver Medallion should now have been released.
Important note: you should already have the Gold Medallion inserted into the clock tower for the Medallion to be accessible.

In the Primary School go to the information desk inside of the school and there are papers on the desk written in Blood. Read them then go to the Chemstry store room and get some bleech on a shelf and go into the Chemistry lab and use the bleech on the hand to get the Gold Sun.

After beating and saving the game the next time you enter the "Options" menu, press L1, or L2. This should reveal a new list of options, including extra ammo. Instead of picking up 1 box the values can be changed as much as 3x's the value, ( 1 box= 45 rounds rather than 15 rounds). Happy hunting!
