Why did it fail so horribly, and why did it get such a low score. I usually roll my eyes at shooters but Killzone is pretty good. I just rented it and played about an hour into the game.
The graphics are pretty good by PS2 standards. Sometimes you don't know what the hell your doing, and the voice acting, "KILL THEM!!!" can get a little annoying, but it's pretty good. I liked how the designers covered up the frame rate glitches by putting them into the strut of your character.
