Extra Weapons

The Chainsaw is unlocked after you beat the game once. In a replay game, you can find it on some logs across from the Silent Hill Ranch in the East South Vale nature trail. It's powerful but awkward to use. You may want to use the Hyper Spray first. To use the Chainsaw, hold R2 and press X. This will perform a swipe at head level. To do a poke attack, hold R2 and hold X tightly. If you just stand with the Chainsaw for a while, doing nothing, James will perform a battle cry, which is quite amusing.

Hyper Spray
To unlock the Hyper Spray, you must beat the game on Normal or Hard Action Level. Then it will be in the motorhome near the west end of Saul Street in East South Vale. The Hyper Spray comes in four colours, depending on your ranking. More information about this is in the Ranking section. The normal and most common Hyper Spray has white spray. This will immobilize certain enemies for a brief amount of time. The best Hyper Spray you can get is the green spray. Instead of freezing enemies, it will kill them. If used on bosses, it will kill them or make them run away faster in certain situations. To use the Hyper Spray, hold R2 and press X to spray for about two seconds. You can hold X to continuously spray and even walk with it. You can even run while spraying on the streets. If you use it a lot, you'll have to shake the can every once in a while, but it has unlimited spray.

Extra Riddle Level

An additional Riddle Level that is a lot harder than Hard. If you enjoy solving the hard puzzles, you'll enjoy this. It requires a lot of thinking and may cause frustration. To unlock it, beat the game on Easy, Normal, and Hard Riddle Levels. Then to play it you have to play on Hard Action Level and Hard Riddle Level. You will select hard but when you save it will say "Extra" and the puzzles are different. When you beat the game on Extra Riddle Level and select Hard Riddle level the next time, it will be just Hard. So you have to beat the game again to play Extra Riddle Level.

Clue of Other Endings

Upon completion of the game for the first time, the next time you play there will be a clue for another ending. There's a memo in Room 205 2F of Wood Side Apartments, next to the sewing machine on the table. It will describe what to do to get one of the three regular endings that you haven't received. If you've gotten one ending, the memo will be about one of the two other endings. If you've received two of the regular endings, the memo will be about the last regular ending. It will only describe the Leave, In Water, and Maria endings. All of the three possible memos are in the memo section. If you read the memo, it will tell you what to do to receive the ending it's talking about.
