Lying Figure

Appearance
Wrapped in a cocoon of flesh, Lying Figures closely resemble patients in straight jackets from a mental institution. Inspiration for the design of this creature came when an employee of Team Silent walked into the office with his hood over his head and his arms tucked into the sweatshirt's pockets.
Behavior
These repulsive creatures walk in a crooked, sporadic path and crawl along the floor, unable to move their arms in their melted flesh. Its attack consists of opening its chest cavity and releasing a form of toxic, green gas.
Strategy
Relatively weak, a melee weapon is ideal as to save ammunition. Lying Figures are more formidable in larger groups or in small hallways in which case a firearm can dispose of them from a safe distance. Once incapacitated, they will scurry along the ground. Running up and delivering a final kick to them will ensure their demise.
 

Mannequin

 
Appearance
The Mannequins are rather pitiable and slow. These bizarre creatures have two sets of legs, with the latter set replacing where their arms should be. Inspiration for the design of the Mannequins came from a German-born French surrealist Hans Bellmer, who took hundreds of pictures of dolls in disturbing poses with bizarre limbs in the early 1930's to protest against the Nazi regime.
Behavior
Without a head and two legs for arms, these creatures walk in a slow, clumsy manner. Mannequins are made of a plastic-type material and release a deep, threatening moan before attacking. Its attack consists of using its upper legs to strike down anything within its vicinity.
Strategy
Like the Lying Figure, the Mannequins are weak and can also be taken down easily with any type of weapon. Unlike the Lying Figure, once incapacitated Mannequins lie immobilized while simultaneously convulsing. Their first appearance is in Woodside Apartments and appear throughout the game periodically afterwards.

Bubble Head Nurse

Appearance
Hospital nurses with a melted face, battered, stained apparel and convulsive stride best describes these creatures. It has been a Silent Hill tradition to include nurses in each installment; these are one of the few enemies to reappear in multiple games. They were first introduced in the original Silent Hill game, accompanied with male doctors (who never made an appearance again).
Behavior
Bubble Head Nurse's intentions are not to heal your wounds. These demonic ladies are typically found in Brookhaven Hospital and walk around with a limp, broken neck. They are typically found in groups combining their attacks for crucial, devestating blows. Most of these nurses use a rusty steel pipe as their weapon-of-choice, but some have been found to use Magnums.
Strategy
The strength of these nurses is fairly impressive. A firearm is ideal for taking them down, as the length of their steel pipes can hit you a good distance away and a melee weapon only does minimal damage. When encountered with a Nurse weilding a firearm being first to draw will determine injury or not.
 

Mandarin

 
Appearance
Mandarins are massive, towering creatures found surfacing the underside of metal grates. Their face consists of nothing more than a tube-shaped limb with an orifice at the end of it. They climb using their massive club hands, which double as mouths that house needle sharp tenticles in them. These creatures made a reappearance in Silent Hill 3, but in the third installment they became larger, bulkier, were able to walk on ground and called "Closers."
Behavior
Found at the bottom of metal grate floors, Mandarins use their club-like arms to scavenge the grates. The cavities at the end of their limbs grip the grates and if a victim walks over them they shoot their spiked tentacles up through their arms and into the victim's feet.
Strategy
Madarins are very scarce in the game, with them only making three major appearances. This creature is also unusal in its behavior and attack methods. For the most part, they will leave you alone and go along their way. However, if you are near or walk over their path they will home in on you and become aggresive. While they can be shot from underneath they can be easily avoided altogether by running past them.

Flesh Lips

Appearance
Flesh Lips' body is melted and distorted while being contained inside a metal-framed box. Within the frame is an indistinguishable blob of convulsing flesh with a pair of feet dangling at the bottom. Inspiration for the design of Flesh Lips comes from the Irish painter, Francis Bacon, who created many disturbing paintings of limbs and flesh coalesced in a grotesque manner. Within these paintings, Bacon made some pieces of figures being trapped and tortured inside metal-framed boxes.
Behavior
This deformed creature slowly slithers and crawls along the ceiling, grasping its victim's neck with its feet. They only appear once but come in mass quantity.
Strategy
Since they only appear once but in large quantities keeping distance and constantly moving is key. Any weapon will make contact with them but because their attack requires being directly above you any firearm can ensure distance and safety.
 

Abstract Daddy

 
Appearance
As a giant bulge of flesh Abstract Daddy resembles a human figure lying belly-down on a flat surface with its extremities peering out the other side of the frame. Its appearance houses inexpicable sexual undertones. Abstract Daddy 's name was influenced by Angela Orosco's tragic relationship with her father.
Behavior
Abstract Daddy stays low to the ground and walks quickly and efficiently. It attacks by standing on its hind legs, trapping the victim in its grip and devouring the prey with its lower orifice.
Strategy
Due to their swiftness and running speed, it is best to take down this creature with a high-powered weapon. Since their attack requires them to be right on top of its victim, a long range weapon can ensure no injury can occur by them.

Giant Cockroach

Appearance
Just as their name implies, Giant Cockroaches are just that; giant coackroaches.
Behavior
These insects creep and crawl on walls and floors while making a loud, chirping noise. If you are unfortunate enough to step on one, they will severely hurt your foot.
Strategy
Because of their small size, melee weapons are unable to reach them. A quick pistol shot or well-timed foot stomp is all that's needed to dispose of these pests.
 

Red Pyramid Thing

 
Appearance
Red Pyramid Thing, also known as Pyramid Head, is the most well-known creature in the game and Silent Hill series. This creature received its name from the large, metallic, pyramid-shaped helmet it wears on its head. With the exception of the helmet, Pyramid Head's physical features match that of a human's. He wears large, leather boots, a dirty butcher's apron and surgical gloves.
Behavior
Found sporadically throughout the game, Red Pyramid Thing serves as numerous boss fights and a means to progress the player further into the game without the intent of battling him. Red Pyramid Thing uses two different weapons throughout the game; a knife and spear. The knife, known as the Great Knife, is actually bigger than most swords. The weight of the Great Knife is so intense, Red Pyramid Thing must drag it step-by-step. In contrast, the spear he uses is lightweight and due to its length he is able to swiftly massacre from great distances.
Strategy
Inherently immune to all attack, encountering Red Pyramid Thing will require two contrasting strategies, depending on your confrontation with him. If met in a common corridor or street, it is best to avoid him at all costs. If confronted in an inescapible area, use a firearm to keep distance and ensure safety until he retreats.

Mary

Appearance
This monstrous, gruesome form of Mary is the final boss in the game. Mary is caged within a metal frame accompanied with spikes potruding outwards from its tips. She has a long tentacle coming from the back of her which is used to wrap around necks for strangling.
Behavior
Hanging upside down Mary slowly slithers accross ceilings. Her body twitches and aches in agony while being contained in a rusted, metal cage. Mary has two attacks: An ambush of butterflies for long range attacks and her tentacle for short range onslaughts.
Strategy
Using the shotgun or hunting rifle is the best tactic as they deal the most damage. Be aware that both these weapons have their drawbacks: Keeping a far distance and shooting Mary with a hunting rifle will cause her to use her butterfly attack. Staying closer to her with a shotgun will increase the chances of her using her tentacle for strangulation. Regardless of what instrument you use, be sure to keep moving as to avoid injury.
