Sure, Sony didn't show this new Killzone 2 trailer off at their press conference, but instead snuck it up onto their press site after the show. Why? That's a good question, but don't worry your pretty little head about it. Just check the video out for over a minute of new Killzone 2 footage, including some more gorgeous explosions. We don't mind seeing grey and green 90% of the time when these super-colorful explosions are our reward. More explosions please.
