realistic 3D?
I really enjoyed the graphics and the 3D effect and didn't notice any ghost images (you can alternate between 2D and 3D at any time during the game). The zombies and other monsters really seem to jump at you, the game is played from a first person perspective with a shaky camera and it's a frightening surprise when you crawl through an opening in the wall on your back and are viewing upwards when an operating saw is falling down on you with it's rotating saw blade.
Spoiler:
There is a playthrough available in five parts on Youtube.If you like "House of the Dead" and are looking for something creepier, than I can recommend "Dark Escape 4D".
