Is Killzone the Halo killer?? Not quite in my opinion. The game has excellent graphics and it really draws you in to the battles which is a good thing to have for a 1st person shooter, but it makes some big mistakes. The game offers a very unique sniper mode where the screen goes red and the crosshair yellow and you spot your target but the control of it is very touchy and hard to pin point your target. But where I believe they really messed up is that their is no jump button. You can't make a 1st person shooter with no jump button. But when it comes to 1st person shooters on the ps2 this one is acually one of the better ones.
