Speaking of the blood, those pools of blood look awesome, not the jaggy splatter, but the pools in which the bodies lie in, it really looks like a thick fluid mass with that subtle refletion of light added to the edge of it... Best example for the is the pool of blood on upper right on the pigcop image and lower left too...

I'd freak out of awesomeness of that blood actually floats out of the bodies in real time like that... My bet is though, that it's probably just put there for dramatic effect, and that the actual blood splatter probably looks more simple...
