The BEST horror game EVER.
As for the graphics, nowadays kinda old, I must admit they're great for 2001, but after having played Quake 4, I couldn't help to notice the flat textures, and the polygonal characters, but as I want to emphacize this is a 2001 game.
The gameplay is really good, mostly due to the ability to blend Spells with weapons, wich gives a lot of versatility despise of counting with a limited ammount of weaponst throughout the game.
The story, ahh the story, alongside the great sound they make this game a Masterpiece, it has one of the best histories in a FPS ever, really immersive, but sadly it gets a little weird at the end (you know kinda like a Stephen King book), and that's the reason why this game it's Almost perfect, the weird final act in wich you fight against (........) haha not going to tell ya, if you wanna know play the game, I assure you won't regreat.
