You will feel you've spent more time waiting for the loads than you have playing the game. Haha, you'll see. Those are the big ones. Wheel of Time Lite best describes the look. The game looks really good, nothing spectacularly imaginative but very serviceable and nicely dark and brooding, very nice rainy weather.
Monsters are properly horrific although the final boss's seams show badly.
Sound also is quite well done. I like FPS's and horror particuarly Lovecraft. It is certainly good to see a game with a good engauging storyline to it also. So many game usually FPS's missed this or bolt it on as an afterthought, not CBU - the story is integral to the game and creates fantastic atomsphere. Not often have I found a game that really honestl makes me jump.
