Survival horror is a video game genre in which the player has to survive against often undead or otherwise supernatural enemies, typically in claustrophobic environments and from a third-person perspective. Survival horror is possibly the only video game genre that is defined by theme as well as game play style. These games can resemble beat ups, point-and-click adventures, RPG and first-person shooters. They all deal with dark, violent and supernatural themes typical of horror movies. This helps to define the genre more than any specific game play mechanic. Most survival horror games are single player only, though a few exceptions have appeared. Player characters are typically armed, but rarely as well-armed as characters in other genres such as first-person shooters. Makeshift weapons such as metal pipes, kitchen knives and other implements are often used in place of firearms. The player's goal is generally to escape from an isolated building or town that is overrun by zombies or monsters. Enemies can be defeated in combat. though avoiding enemies is often preferred or even necessary in order for the player to progress.
