Good but not ace.
The 3rd person change from the orginal killzone for ps2 works well and they have made good use of it.
This game will keep the average gamer busy for a while but most people wont have the urge to play it over and over again.
The AI in this game aren't exactly intelligent and if they see their mate get shot they continue to stroll into the line of fire.
While your health and ammo gets low easily plenty of suppy crates around so no matter.
A good game and worth the purchase for your PSP
