Round Four: Enemies

Killzone 2

It's not hard to spot who the enemy is in Killzone 2. Your gas mask- donning foes come in several varieties, but they all retain that basic look: glowing red eyes, smooth black Darth Vader-like suits, and booming voices that sound like they're gargling broken glass.

Halo 3

Halo 3's enemy roster is not as simple as Killzone 2's. In the game, you're faced against several different breeds of enemy including the grotesquely-misshapen The Flood, gorilla-sized savages called Brutes, miniaturized low-level enemies called Grunts, and several others.

THE WINNER: Killzone 2

Quantity conquers quality in Round IV of Killzone 2 vs. Halo 3, as Halo 3's colorful assortment of enemies doesn't quite compare to the unforgettably diabolical Helghast.

Round Six: Multiplayer

Killzone 2

Killzone 2 features an immensely customizable multiplayer experience, one that includes clan matches, an exhaustive trophy system, and various character classes you can play as like invisibility-suited Scouts, medics, engineers, and several others. You can even wager bets on the outcome of matches to earn points.

Halo 3

Even nearly two years after its release, Halo 3 remains one of the most played games overall on Xbox Live--last year it was ranked the #1 game played online on Xbox 360. From the numerous addictive multiplayer modes that everyone loves like Oddball, King of the Hill, and of course Slayer, to new incredibly fun game types like Rocket Race VIP where teams of two ride together on mongooses while one player shoots rockets from its back, Halo 3's multiplayer has a lot to offer.

THE WINNER: Killzone 2

Though not tried and true as Halo's multiplayer experience, Killzone 2's multiplayer wins Round VI, giving it a one round lead over Halo 3 so far in this match up. I'm confident that gamers will be sucked into Killzone 2's Call of Duty-caliber multiplayer experience.

Final Round: Extras/Replayability/Overall

Halo 3

One of Halo 3's best extra modes is Forge, where players can tailor their very own multiplayer experience, setting up everything they want in the game from specific rules to the vehicles available on the map. Its replay value is high too-even though the game is somewhat dated and not as sexy as say Call of Duty: World at War/Call of Duty 4. It's still played a great deal online and many gamers will continue to play it even after Halo 3: ODST releases.

Killzone 2

Killzone 2 doesn't have any crazy modes outside its single-player and multiplayer options, but the years it's taken for Guerilla Games to polish and perfect this beast of a first-person shooter's two main game types really shows.

WINNER: Killzone 2

PS3 fanboys hype a games for it qualtiy

Xbox Fanboy hype games for its quantity  (if thats the case Wii-Fit Is over all)......nuff said

There are so many differences between the two.

Halo is almost an arcade like experience with power ups, crazy weapons and jumping phisycs...it has an easier learning curve and is much more forgiving for new players. But thats not to say that halo has no depth. Slayer in halo is much more of a team based and startegy game than in COD.

COD is more realistic and a lot more frantic which appeals to a lot of people more...

I personally dont like COD's approach as it seems like an evolved version of rainbow 6 or Ghost recon...games i never liked.  I preffer and always have games like Quake, Unreal, Duke...and Halo 3 is that type of game with its own spin.

While Halo is fast like Unreal or Quake, it certainly takes a whole more to actually kill someone.

And I think the speed of the game puts CoD as a slower more tactical game. And I don't think it's anything like the Tom Clancy games. I really don't like them but understand why some do.
