Very nice video. Hadn't it been for the low resolution, then I would've been freaked out by those sudden scares, the zombies popping up and all. Also, the HDR effect in the vid, it seems like it works very well! I'm still surprised at how well you've got shaders to work. Very nice, will definetly try to get ahold of the game once it's done and when I have money.
And about the shaders, I'll e-mail you sometime tomorrow, I think. I don't have a lot to offer, but I hope I can convince you to let my greedy soul have the effect-awesomeness.
