An FPS for the PS3, releasing Feb 22, 2010. Often loved by PS3 owners, and hated by Xbox owners. Because of this, it is hard to find an unbaised opinion about it, so play it yourself before you let any one tell you that it is a good or bad game.
PS3 user: Killzone 3 is "The Halo Killer".
Xbox user: No Halo is way better than that peice of garbage.
Sensible Person: Niether of one have ever played both games. You have only played the one on your console, so can either of you really make a fair comparison?
*PS3 user and Xbox user go into rage*
