Take away this one crucial factor and, actually, Killzone doesn't seem all that different, special or exciting. Harsh? Not at all. Yes, the graphics look very presentable in the screenshots, but actually in the 'flesh' don't really have the wow factor you might have been anticipating. It's a very gritty, grainy, dark approach that's by no means unattractive (and in some respects suit the premise), but it won't have your eyes bulging out of your head wondering how they managed to drag such trickery out of the PS2. There's little in the way of lighting effects, very little in terms of physics routines (enemies slump down dead convincingly, panes of glass crack and smash and the odd water cooler gets knocked asunder, but that's about it), texture detail isn't up to a great deal, the outdoor foliage could be better and the frame rate appears to be around the 30 mark. On top of that, so far we've seen just one enemy in the opening three sections of the game over 12 levels - and unless there's a bit more variation, we're slightly concerned as to how the single-player facet of the game will hold our interest.
