Portal: The Nightmare mod

lol well, i'm adding color correction and soundscapes right now, but it wont be very very scary, but scarier than portal! The word Nightmare refers to 3 things: First: Nightmare because it's a Nightmare of the test subject! Second: Since Portal is Easy, the worst Nightmare of the test subject would be that that the Aperture Science test is hard, so it refers to hardness! Third: Refers to a little bit of creepyness ;)

But you must put it in count that creepyness is a relative word. You are maybe not afraid from spiders for example, but I try to keep a distance even from a little, harmless one.
What could really can make much of the gamers feel fear are: Dark atmosphere (so this bright one is not to good), emptyness (lucky for you, it's already provided in portal), Scary sounds, well placed blood stains, flashing lights or no lights at all, moving shadows that disappear when you might see the person or thing "casting" it, etc. Just think of Bioshock, F.E.A.R. or what the hell, even the asylum levels of Psychonauts, and you know what I'm thinking of.
But no headcrab zombies, they are not scary anymore.

thank you very much for the advices!!! i'll try to follow the most of them! i think i prefer making it harder than creepy ;) dark rooms and scary flashy lights without any soundscape (total silence) will be there, but not too much =)
