In order for one game to "kill" another game it has to draw the fan base away from said game.
One could say that Warcraft 3 was a Red Alert 2 killer, or that the Wii is a PS3 killer for example, but to claim that any fps game is a Halo killer is absurd considering that Halo 3 has a following that's probably 2 times bigger than it's closest competitor.
I don't know a single person that stopped playing Halo 3 and took up KZ2 full time. So in conculsion, KZ2 is not, and never will be a Halo killer.
