It's kinda derivative of Resident Evil. However, there's not nearly so much fighting; your character is just a "normal guy" with no military training, nor any real fighting ability for that matter. The game is very dark & dimly lit, and extremely spooky. Creep lighting and eerie sound design injects a surprising amount of fear and dread into the game. But it just moves a little slow for me, and there isn't enough action.
I liked SH1 enough to buy #2 when it came out for the P2, but I never finished the 2nd one. It just didn't hold my interest. I will admit to being very fickle when it comes to games. Still, it has a lot of cool elements. It's now available for the 'box @ $20. Worth a look if you're a patient sort that values depth over hacking and slashing, 'cause there really isn't any hacking or slashing!
