This looks excellent! How much of the media is custom, and how much from model packs? I don't recognise a lot of it, but then I never bought any model packs, hehe.
If you have a good plot to match the great level, this will be a real gem!
As for scary stuff - well, sounds are always good. A creepy BUT VERY QUIET ambient track looping in the background is quite effective, but you MUST NOT go over the top with it: it needs to be brooding horror, not stomping great rock tracks all the time. And some scary scenes? Here's one I thought of a few weeks ago: a room full of people lying on the floor. They are face up, breathing shallowly, eyes wide with fear. They are completely conscious, and aware of rats or cockroaches etc. skittering around the room, nudging their clothes, crawling over their bodies but they are totally paralysed. They can breathe, but they can barely move their eyes. They certainly can't speak. Picture just this room, huge, monumental, with maybe two thousand people just lying like that in rows from one wall to the other. You'd have to think up WHY they're like that, since I know nothing about the plot, of course.
I'm not actually a Kiwi, I just randomly thought it up one day.
