Recently I saw this trailer, and I freaked out:

I did not see that coming.

So what was the videogame trailer that scared you the most?

woah shit! that was unexpcted

dementium 2

i was like this a week ago when i finished surgery, yeah i puked blood all over the place, and kept bleeding through my nose till about half an hour.

omg, that was nuts... and now i'm interested XD

I'm interested too, but it's ps360

and PC n_n

lol i was expecting something worse but was still freaky.. if this is based on alice in wonderland it would be really interesting to see what the do

cool trailer, but with a bit of knowledge of who is making the game it's absolutely no surprise.

Ever heard of American McGee ?

This was shown prior to Silent Hill 3 release (turned out to play over the menu screen) which is what I consider disturbing.
