The Halo multiplayer is better than COD. You actually need skill to shoot someone, because, unlike COD, a few headshots will only drain the player's shield. Halo has a MUCH better physics engine. There's no preprogrammed animation for headshot or anything. A shot to the heart will make the player twitch to his left as he dies. And the vehicles are much better too. Alien hovercraft + good ol' human jeeps makes for a heck of a road battle. Also, some people say that Halo has 'unrealistic' weapons. As far as plasma weapons are concerned, its a lot better than some of the crap they have in COD. Also...wait am i talking too much? I could go on forever but I don't think people have the time to read these lectures. Anyway, these points should be enough to vote for Halo. Oh oh, one more thing. BEST CAMPAIGNS EVAAAA!
