After loosing consciousness, he wakes up in Silent Hill and decides to see what has happened to the girl.

The game plays similar to other Silent Hill games. However, the game has a larger emphasize on melee weapons, and melee weapons now can only be used a limited number of times before breaking. The game also incorporates improvised melee weapons like old TVs or bottle of medical alcohol.
