War is hell, but Call of Duty 4 is heaven
Call of Duty 4: Modern Warfare is an outstanding game. The gameplay diverts itself from its WWII counterparts, and it turned out to be a great decision. There is practically nothing wrong with Call of Duty 4. Practically Nothing.
The core gameplay is about the same as the previous Call of Duties. The L1 button brings the gun up to your face so you can aim. But what separates this one from the others is the variety in gameplay. The guns are great and realistic and powerful. The single player campaign takes you through the Middle East as an American Soldier, through Russia as an SAS soldier, and through Chernobyl as a flashback 15 years in the past. There is one mission where you are in the seat of a bomber plane, and you get to shoot bombs at the little dots on the screen. It's really incredible to watch the little guys fly all over the screen. Also worth adding is the ability to shoot through plaster, wood, or other thin materials. This is really helpful both online and in multiplayer. Also, COD 4 uses the same health system as COD 2, as your health regenerates as long as you stay out of sight.
The AI in Call of Duty 4 is just incredible. Enemies come in vast numbers, and will use flanking techniques and will have squad tactics of their own. It is really top notch in gaming today.
The campaign is only about 6 or 7 hours, but the overall quality of it is through the roof. Not one moment is boring, as you will develop a camaraderie with your squad members, especially Gaz and Captain Price. The Story in COD 4 is actually really good, as opposed to other shooters. The world is on the verge of a nuclear war, and you and your 5 or 6 squad members will have to save the world on your own, it seems. There are themes of genocide and injustice, and those are really captured in the campaign.
The multiplayer of COD 4 is the best of any shooter. There are 16 maps right out of the box, all of which were probably seen at one point in the campaign. There are a ton of different game modes like the normal team deathmatch, as well as a one on one cage match against another player. There's sabotage, and domination, and many other great games to be played. What's cool is the ability to create a class. As you play and become better, you will unlock upgrades such as different attachments and camouflage for your weapons, as well as perks like explosives. Other perks include the ability to upgrade you bullet damage, as well as your own health, the ability to remain unseen on enemy radar, and much more. If you get a 3 kill streak, you will get a UAV recon, which allows you to spot enemies on your radar, 5 kill streak is an airstrike, and a 7 kill streak is helicopter support. Playing online will have the Blu Ray in your hard drive forever. You are always motivated to do well, but if you don't there is still no pressure because it is still so much fun. There's also challenges to do, such as getting 150 headshots with a weapon, or running 10 miles. These challenges will get you XP to rank up. Online is incredible fun in COD 4.
It may not get noted a lot, but COD 4 is one of the most photo realistic games ever made. The character models are incredible, the lighting and shadows are great, and the buildings and textures are some of the best on a console. It doesn't hurt that the frame rate is silky smooth.
There's nothing really else to say, this game is almost flawless. But it is still missing offline or online coop, and the campaign could have been longer. Other than that, there is not one, NOT ONE reason you shouldn't get the game. Call of Duty 4: Modern Warfare is one of the best games ever made.
