This is a u cut gem that should be played by everyone at least once. Back when it was released, technical limitations and ridicoulous development (seriously, some one should make a documentary about making of STALKER) held it back from being perfect. Nowadays tho, with community patches this game is a must play. There are no other games like this - a blend of FPS, Open World survival and atmospheric horror. Add in some slight RPG elements, several ending based on your actions and epic setting - you have to play this. For me personally, SHOC will always be one of the games that shaped me as a person.
