Hot dang that looks good, and a trailer with actual gameplay footage, those seem to be getting rarer and rarer.
I never finished the first crysis, I kinda got bored an hour or so in but I want to finish it now so I can look forward to playing that!
The water, pause it, looks pretty crap when you do but in motion, really does look something else.
Also, awesome choice of music, same NIN song as in one of the 300 trailers.
EDIT: just checked for Kaburan, it's "Just like you imagined".
