2004 has been a remarkable year for games with some incredible titles released in a very short time. Two of the biggest games of 2004 are Halo 2 and Half-Life 2, both highly anticipated fiction first-person shooters. These two games are similar in nature. Both are shooters, both are based in a science-fiction storyline, both main characters wear cool suits and both are long-awaited sequels. Though Halo 2 and Half-Life 2 are currently exclusive to their respective platforms, we decided to put these two titles against each other to see which game outplays the other! It's Freeman vs. Chief in this Face-Off!

I love the fact that Gordon Freeman's just an average Joe who made a huge mess, but the guy isn't exactly the life of the party, so I have to give it to Halo 2's Master Chief. True, he's just a super soldier, but the guy's got tons of personality, loves making smart comments before wasting the enemy, and let's face it; he looks $%^%$&* cool! Definitely a sweet Halloween costume if I ever saw one. Trust me. There's a reason why there aren't a whole line of Freeman action figures.

Gordon Freeman is probably one of the most unique characters around, mainly because he's kind of a patron saint for geeks everywhere. He's a theoretical physicist who graduated from MIT who happened to be caught up in circumstances that are far beyond him. Without his hazard suit, he is as vulnerable as anyone else to the alien assault. He has to be careful even with his suit, since its protective shield doesn't recharge on its own (unlike a certain Master Chief's), forcing him to rely as much on his wits as his firepower. Used as a pawn by the mysterious G-man, Gordon perseveres in saving himself and humanity, crowbar in hand.

Winner: Halo 2

Bungie's sequel comes fully loaded with all sorts of new gameplay additions. Duel wielding opens up a whole new level of strategy because of the various weapon combinations, but the ability to board vehicles, the improved graphics, fleshed out story, and Xbox Live make Halo 2 the most improved sequel to come out in a long time. As for Half-Life 2, it no doubt looks amazing, and the AI is great (but by no means comparable to Halo 2 on Legendary), but I'm not sold on its physics engine. Impressive, no question about it, but since the game released a year late, realistic physics have been done before in other games.

The most prominent upgrades include the graphics, powered by Valve's Source engine, which creates life-like characters with realistic facial expressions, and the inclusion of the Havoc 2.0 physics engine. That means things fly, fall, and react the way they are supposed to. With these two things combined, and the upgraded artificial intelligence, Half-Life 2 creates a gameplay experience that is completely unlike any other. Additionally, a couple of vehicles have been added, including a versatile water craft and a dune buggy. The inclusion of the Steam service means that users will no longer have to periodically search the internet to keep up with the latest updates and patches.

Winner: Tie!

Halo 2 easily trounces Half-Life 2 not necessarily because its graphics are better per se, but because they're the most consistent. Halo 2's spectacular lighting, particle, and bump mapping effects look gorgeous no matter what Xbox the game's played on. Period.

Half-Life 2, hands-down, has the best graphics of any game currently on the market. In this department, it has no rival. Backed by the Source engine, which brings NPCs to life by showing a full range of facial expressions and emotions, this game creates an incredible sense of immersion and attachment to the characters. Lighting and shadows play a huge role, as do fire and water. The realistic blood splatter is absolutely amazing, and seeing a soldier flinch after getting shot never gets old. After seeing all Half-Life 2 has to offer, no other game will measure up.

Winner: Half-Life 2

Composed by Martin O'Donnell and Michael Salvatori, Halo 2's soundtrack is haunting as well as adrenaline-charged. They pumped it full of new content while still retaining some of what made the first game's score so inspiring. Heck, I'm still humming the game's main theme even after all these years. Does the Half-Life series even have a main theme? Lastly, I'll always love Halo 2's soundtrack because it has its own personality. It can stand alone apart from the game it's married to, and for that reason, it excels above the competition.

Players probably won't be running out to stores to buy the Half-Life 2 soundtrack, but it does what it needs to do. The music creates a sense of tension and suspense as Gordon makes his way through a fetid sewer system or darkened alleyway. The weapons sounds are exactly what they need to be, with huge explosions for the rocket launcher and equally threatening effects for the pulse rifle. As for the enemies, the hisses and clicks of antlions before they attack are always menacing, and so is the distant howl of an evolved head-crab zombie. Let's not forget the superb voice acting for all the characters. This is a game that is guaranteed to keep players on the edge of their seats.

Winner: Halo 2

Halo 2's open-ended gameplay is unlike anything I've ever seen on a console. You're really free to go about your business anyway you like. Snipe enemies from a secure location, steal vehicles and run them over, or hop aboard a Wart Hog with some fellow marines and go in guns blazing. In addition to that, the ability to select from several different difficulties breathes new life into the game, and playing through the entire single-player campaign with a friend is always an amazing experience. Lastly, Halo 2's control scheme is not only incredible for a console, but it's influenced numerous developers who've copied it for their games. As for Half-Life 2, it's pretty much a straight-forward shooter whose controls do nothing to advance the genre.

Half-Life 2 isn't all about running and gunning. There are significant parts of the game that require some brainpower to go along with the firepower. In fact, the whole beginning sequence requires that you get by with no weapons or protection at all. The physics engine allows for a great deal of creativity when dealing with the mass of oncoming assailants. Why bother wasting ammunition on soldiers when you can use a giant magnet to drop a huge steel container on them? The gravity gun offers even more variety. Catch enemy grenades in mid-air and throw them back. Pick up intelligent land mines and strategically place them. Push a car off a cliff. The material physics are equally impressive, as planks of wood splinter and break under your crowbar. In the bay and surrounded by soldiers? Use your boat to ram through the weak beams holding up their walkways and let gravity do the rest. You'll often have to stay on your toes, because aliens aren't the only things you have to worry about. Sometimes the environments can be just as dangerous, with lakes of toxic waste and electrified waterways in your path.

Winner: Tie!

Half-Life 2 deserves a nod because of the mods that'll be released, but let's take a look at what's in the box. Counter-Strike Source isn't anything we haven't seen before. As for Halo 2, it's rocked the console world with silky smooth Xbox Live play that features numerous game types and all sorts of cool maps. Plus, it's super easy joining clans and keeping track of your friends. What this all means is, in the annals of history, Halo 2 will be remembered for the positive things it'll do for the industry. With its help, online gaming will become more mainstream, and its impact may influence companies (like Nintendo) to join the fray.

Half-Life 2's multiplayer is practically a whole game in itself. It is a remake of Counter-Strike (originally an extensive Half-Life mod) using the Source engine, aptly named Counter-Strike: Source. While the maps are upgraded carryovers from the original mod, the addition of the physics engine renews the game's playability as far as tactics and strategies. Objects can be moved to block off or impede key areas. Crates break apart when shot. The multiplayer experience is as intense as ever, and the mod community will guarantee that it stays that way. Throw in the fact that Valve recently released Half-Life 2: Deathmatch, and you have everything you could possibly ask for. Use the gravity gun to pick up anything from a desk to a urinal and launch them at your opponents, within maps where the environment is as key to your success as your abilities. Gameplay is pretty smooth and generally lag-free, while Steam keeps all game versions up-to-date and connected.

Winner: Halo 2

Halo 2 is without question the most story-intense first person shooter ever released. I'll give the nod to the original Half-Life for what it brought to the genre, but after a few books detailing the Halo saga, fans can truly immerse themselves in this rich sci-fi world full of history. As for Halo 2, its narrative is beautifully woven throughout the game via cut scenes and in-game chatter between characters and I was completely immersed throughout the entire experience.

The graphics and weapons would be nothing without the mysterious story keeping it all together. Half-Life 2 doesn't have any load screens (except for pauses between areas) or cut-scenes outside of people talking to you in an effort to create a realistic, connected world. While this sequel seems like the middle part of greater story arc, leaving many mysteries unsolved, it is nonetheless compelling. The realistic look of NPCs and fantastic voice acting keeps players deeply immersed as they try to find their way in a world that has been conquered by alien invaders. This is one of the main areas that really sets Half-Life 2 apart from Halo 2. You're not a genetically enhanced super-soldier fighting off aliens invaders. The aliens have already won. You've just unwittingly been made the leader of the rebellion.

Winner: Half-Life 2

It's true that most of the weapons from the original Halo were carried over to the sequel and that's definitely a great thing. The Plasma Pistol is essential for breaking down enemy shields, the Plasma Rifle kills aliens in a hurry, and the M19 SSM Rocket Launcher and M90 Shotgun spell doom for online foes, but there are scores of new and cooler weapons in Halo 2. The Wart Hog's M68 Gauss Cannon is a life saver in capture the flag, the BR55 Rifle is a great close-range and distance weapon, and other notables, such as the Particle Beam Rifle, Covenant Carbine, and the SMG really enhance the gameplay, and I'm just getting started! However, you can't talk about Halo 2's weapons without mentioning the Covenant Energy Sword. It's simply one of the most intimidating weapons ever put into a videogame. During multiplayer, hiding the sword and then unleashing it upon your unsuspecting foes produces priceless reactions.

Many of the weapons from the original Half-Life were carried over into Half-Life 2, but that doesn't mean there aren't a few new toys to play with. The most significant weapon is the gravity gun, which shows off the spectacular physics engine by picking up objects like barrels, debris, grenades, and circular saws and launching them at enemies. It can also push large objects like cars around. Not only that, but you can capture small mechanical enemies and break them against each other. New weapons also include the pulse rifle, which amounts to a very powerful machine gun with a grenade that literally vaporizes targets, and "bug bait" - a gland stolen from an antlion queen, used as a biological weapon. Using its scented secretions, you can use it to call a small army of giant insects to your side, then instruct them to attack a specific target. Classic weapons include the trademark crowbar, the devastating Magnum revolver, the silent crossbow, and the ever-useful laser-guided rocket launcher. Most weapons have a secondary fire, and you'll probably use a combination of all of them in order to get through alive.

Winner: Half-Life 2

The key to crafting a great story is to instill every character with an individual personality, and Halo 2's Covenant is among the most memorable bad guy ever designed. The Grunts, Brutes, Elites, and the rest of the game's motley crew of monsters all exude a personality that stamps itself into your brain. Not only are they always communicating, but their lifelike animation as well as their advanced AI really combines to create foes that look and sound extremely realistic. Like the Master Chief, there's a reason why the Covenant are part of a toy line, and it's not just because of mass marketing.

Half-Life was all about beating back monsters from another dimension before they could reach Earth. In Half-Life 2, not only have they reached our planet, but they've taken over. Now, the Combine are everywhere and they're all after you. Enemies range from the biological to the mechanical. There are fully outfitted, genetically enhanced humans that operate like storm troopers. Thanks to their excellent AI, they make great use of cover and won't hesitate to use grenades to flush you out. Head crab zombies are abound, but now there's an evolved version that is faster, stronger, and more deadly. Not to mention a creature that hurls super headcrabs at you like grenades. Machines include hunter drones that fly around with sharp whirring blades, and magnetically charged spheres that attach to the sides of your vehicle to either slow you down or shove you off a cliff. Antlions hiding beneath the sand turn a picturesque beach scene into a menacing place of danger. Giant striders patrol the area, and rock and shudder when hit by a rocket. The skies have heavily armed ships looking for you. The enemy is here, and no place is safe.

Winner: Halo 2

Half-Life 2 is amazing no question, but Halo 2 is the superior game because it's the total package. It plays great, looks gorgeous, has a phenomenal soundtrack, and an even better story. Plus, its online multiplayer is simply fantastic and a revelation for millions of console owners. Counter-Strike Source isn't enough, and while the future Half-Life mods will be neat, how long are PC gamers going to have to wait for them all? Plus, the possible need to upgrade video cards or even computers to play the game make it the kind of shooter you can wait to play. Halo 2's here now in all its glory, and you can pick up the game, an Xbox, and a year's worth of Xbox Live for under $300! Pound for pound, Half-Life 2 simply doesn't match up.

For the most phenomenal fist-person gaming experience, the first and last answer is Half-Life 2. The incredibly realistic graphics, the fantastic use of physics, broad range of weapons and sense of open-ended gameplay make this one of the best titles on the market. The Counter-Strike multiplayer is very impressive, and practically counts as a second game right out of the box. Inevitable mods will make sure that multiplayer action never gets old. While Halo 2 shows off some Xbox Live multiplay, they are mostly enjoying capabilities that were available in the original Half-Life. Plus, community mods don't play a role, so Halo 2 can never be anything more than Halo 2 - while the original Half-Life was reborn into games like Day of Defeat and Counter-Strike. Valve has set the bar really high and managed to up to its own hype, despite a development that was marked with a multitude of setbacks. Every once in a while, a game comes out that justifies a major computer upgrade, because the experience is so significant that it becomes a milestone in video game history. Half-Life 2 is that game, and its influence will resonate among games to come.

Overall Winner: Halo 2

By the slimmest of margins, Halo 2 pulls in the victory over Half-Life 2! When it comes to confronting aliens, it looks like the Master Chief has got what it takes! But don't let that stop you from picking up both games, as each will give an incredible experience that can't be missed!
