i love this game and thought id start you off with some simple discription for the first game;

Seven years ago Harry Mason and his wife found a baby by the road and adopted her as their own, naming her Cheryl. Though his wife soon died, Harry Mason continued to love Cheryl as his own daughter.

At the start of the game we find Harry Mason and Cheryl going to the resort town of Silent Hill. Strange events occur before they have even entered the town. A cop on a motorbike drives past them and only moments later Harry sees the bike lying by the side of the road and the cop is nowhere in sight. Soon afterwards a figure suddenly appears on the road, causing Harry to swerve the car and slide off the road. When he regains consciousness, Harry discovers that Cheryl is missing and that he has slipped into a strange dimension shrouded in fog. It's soon clear that this place is unlike any place he's been before. Strange creatures lurk within the fog and as Harry follows what he thinks is his daughter's silhouette all over town, he realizes that the town has a darker and more dangerous side to it.

You then carry on to fight some really creepy creatures with some really shitty weapons, but it gets worth it to see the awsome endings that you can recive stated below.

Bad: In this ending, attained by killing Cybil and not rescuing Kauffman, after finishing the game the player sees that Harry is dead and still in his crashed Jeep, suggesting the entire game was a hallucination.

Bad+: If the player rescues Cybil, but not Kauffman, this ending is achieved. Cybil is present for the ending. Instead of fighting the demon god as the final boss, Harry instead fights Alessa. After defeating Alessa, Harry hears Cheryl's voice through the defeated Alessa one last time. Harry sits on the floor distraught because he realizes he has lost his daughter. Cybil tells him that they need to go, but they are trapped, as fire rains and otherworld starts collapsing around them.

Good: This ending is achieved when the player fails to rescue Cybil but manages to rescue Kauffman. Kauffman shows up at the final boss confrontation with the demon god. After Harry defeats the demon, Alessa reappears and hands Harry a baby. She then creates a portal where he escapes. Kauffman makes a move to follow him, but a blood-soaked Lisa Garland crawls up through the floor and holds him back, dragging him screaming into an unknown area. In the last scene, Harry ends up running on a dark street when the game ends.

Good+: If the player rescues both Cybil and Kauffman, this ending will appear. Both Kauffman and Cybil are present for the final battle with the demon god boss. After the demon god is defeated by Harry, Alessa reappears and hands Harry a baby and creates a portal for him to escape. Both he and Cybil go through the portal that lands them where Cheryl was initially found seven years ago. Cybil is then shown standing next to Harry as he looks at the new baby he has, and the game ends. After obtaining this ending, the opening video, in which Harry and his wife find Cheryl on the side of the road, is changed to the ending video where Cybil is with Harry looking at the baby instead. Kauffman's fate is the same as you would achieve if you received the good ending.

UFO: This is a joke ending, and not considered an "official" ending by many fans, who consider it to be more of an easter egg. Harry uses a 'channelling stone' in certain areas, noticing the presence of UFOs after doing so. The final time it is done, on top of the lighthouse, a UFO lands and abducts Harry after he asks if they know where his daughter is, "She's about this tall, black hair" (a humorous reference to the fact that Harry's line whenever he meets somebody throughout the game is "Have you seen my daughter?", etc.) A credit sequence is then played where a song plays. A voice can be heard repeating the name "Silent Hill" occasionally. The abduction scene is presented in several still images referencing the Mars attacks series of trading cards. This concept became so popular with fans that Team Silent included alternate UFO endings for both Silent Hill 2 and Silent Hill 3. These endings appear to create a sepreate storyline, with the third game's UFO ending refering to the first game's UFO ending.

NOTE: I have posted some of the endings in the video library but not all of them
