DEMON LIZARD

Battle: After the turnstiles in the Alternate School.

Attack: Watch its head as it tries to knock you off balance. Once you shoot it , the thing becomes more agressive!!

Shoot At: It's head. 

Tactics: Firstly, run around the room and wait for the lizard to start coming towards you. Shoot it several times in the head before running off and repeating the technique again. When it begins to open its mouth to devour you, fire off some shots into the lizard's mouth. Walk backwards as you shoot.

DEMON MOTH LARVA

Battle: Shopping Mall, Alternate Silent Hill.

Attack: Disappearing underground, the Larva Boss will re-emerge close to you and omit poisonous cloud into your face.

Shoot At: It's head

Tactics: Use the Rifle. Move onto the metal grating in the room - this will stop the Larva surfacing close enough to hit you. As soon as you hear it's telltale rumble, hit R1 or L1 to move to the side - you'll be out of harm's way, but close enough to inflict some damage with your firearm. Remember to shoot the head- antother part of its body is a waste of valuable ammo.

DEMON MOTH

Battle: Opposite Alchemilla Hospital, climb the metallic staircase to the roof for a better shot.

Attack: This Boss has two dangerous attack methods; first it'll spray a deadly cloud of venom in your face, then it'll fly into you, giving you a hefty whack and knocking you off balance.

Shoot At: Anywhere on the body.

Best Tactics: Although dangerous and large, the Moth is easy to avoid. If you have loads of ammo and health drinks to spare, just stand there and fire off shots as quickly and as accurately as you can and you'll soon finish it off. If ammo supplies are low, keep moving until the Moth has let off its poison cloud. Turn immediately, fire off a couple of shots, then get moving again - only this time in the other direction. Although this is more time-consuming, it will save your supplies.

DEMON CYBILL

Battle: Lakeside Amusement Park, Alternate Silent Hill.

Attack: Her firearm can finish you with two shots.

Shoot At: Just shoot her! Unless of course you are after a different ending- in which case....

Tactics: Shoot at her with one of your stronger firearms from a distance, making use of your L1 and R1 buttons to avoid her fire. When she stops to reload, run forward and empty as many bullets into her as possible. Repeat this as many times as necessary.
If you use the Unknow Liquid and conclude the battle without killing her- wait until Cybil stops to reload before approaching her.Remember, she only has to hit you twice and you're dead.

SAMAEL

Battle: After the Child's Room in Nowhere at the end of the game.

Attack: With two main attack methods, this Demon can finish you off quickly if you don't keep an eye on your life gauge. It'll either fire at you with a strong energy blast or shoot several lightning strikes your way.

Shoot At: Anywhere on its body- although it's attack methods are predictable, Samael stays routed to the same spot, which makes it easier for you to avoid its blasts.

Tactics: Equip the strongest firearm you have and chose one of the following three options:

    Tactic One:
As soon as the battle begins, fire off as many Rifle rounds at the Winged Demon as you can before it starts shooting its electrical blast. Then start running around in a big circle, avoiding any of its strikes. As soon as it lets off a blast, stop, fire once or twice, then get running again.

   Tactic Two:
Only try this if your ammo and health supplies are good. If you have lots of health, try the technique you used to dispense of the Moth. Use your Rifle or Shotgun and fire at close-range, remembering to knock back a health drink after each hit from the Demon.

  Tactic Three:(My thanks to the Silent Hill Forum for this one) 
Before you go through the door in the Child's Room in Nowhere, get out your firearms and use up all your firearm ammunition.
Enter the arena, and the battle will commence as usual. Select your Handgun, Shotgun and Rifle and fire once using each gun to show that you're out of ammo. Then just keep running. If you avoid two consecutive hits from the Boss, the Winged Demon will collapse to the floor and the battle is over.Easy!!
