Disappointing entry into the horror genre
Graphically, Nocturne is a beautiful game. The engine works great with lighting and shadows. Generally has good voice acting. Interesting premise and fairly good level design too.
1. Nocturne really isn't that scary.
Why? Because the main character doesn't give a damn. He doesn't react to the monsters, he just shoots them. So if he isn't concerned why should we be?
Also, the only scares Nocturne can establish are the surprise scares- monsters jumping through windows, etc. No real sense of dread here.
2. Controls suck.
The Nocturne engine looks great, but there are some serious clipping problems. Shooting works fine, and the character models sustain localized damage (ie, you can shoot someone's arm off,) but hand to hand combat is terrible. Running, walking, jumping are all way too challenging and inaccurate.
3. Bad camera.
There are terrible camera angles in this game. Alone in the Dark, Resident Evil style camera angles work well within buildings, but sections of Nocturne involve running through the woods. This is horrible. Many times I fell to my death, only because the camera angle did not show how close I was to a cliff. The combination of poor camera angles and poor controls killed me more than any monster.
The Bottom Line
Poorly designed "survival horror" game focuses too much on graphics not enough on gameplay.
