Gamepro -- Killzone 2 VS Halo 3 (Is KZ2 a Halo Killer?) YES IT IS!!

[Squilliam]

In my obviously subjective opinion, Halo 3 wins everything except graphics when comparing the two games.

Halo is just too uber, when Killzone 2 can boast 150 hours average playtime then some people can talk, until then its obvious which game remains top dawg.
