Metal Gear Solid 4 is the best game in the series, and pushes the boundary for a cinematic game experience.
Metal Gear Solid 4 is easily one of the most technically proficient games to date, from the amazing character models, from cut scenes seamlessly switching into game play, and some of the sheer sizes of some set pieces, to all the things that are going on at once.
The story as like all the other Metal Gear games: complicated. But if you've played the other games and had a decent grasp on the story line, you should be okay with MGS4's story. The game introduces a new character, Drebin, a gun launderer, who acts as an outlet to unlock weapons dropped from enemies, buy ammo, and buy new guns.
The game play is as solid as ever, and for the first time, has a cross hair aiming system, which works beautifully in third person mode. The game is meant to be played as a stealth game, but you can also go guns blazing, although you will most likely die more often with this approach. The game is also filled with humorous items such as Playboys and cardboard boxes that players of the other games int he series will be familiar with.
The game also has a fair diversity of environments, ranging from the Middle East, South America, Eastern Europe, and Alaska. The pacing of the game is very nice and some set piece battles such as a couple vehicle chases and the chance to control a Metal Gear are extremely fun and rewarding.
By the end of the game loose ends are tied up, and there really aren't any questions left to be asked in regards to the plot. The game has plenty of replay value whether it be Metal Gear Online, or playing through multiple times on higher difficulties to unlock new camos and weapons.
Overall, Metal Gear Solid 4 is an amazing game that no fan of the genre should miss, and is a must buy for PS3 owners.
