One of the most perfectly executed games in gaming history.
But this game truly deserves the marks of perfection.
Everything is done right.
The graphics are astounding. Sprinting through the enemy lines with fear of an enemy picking you off through the garbage and debri-infested streets. Or creeping back in a bush under the lavish, green brush, waiting for that enemy soldier to peak his head over the wall for a perfect head-shot.
The sound envelopes you into the surroundings and everything just makes it seem "real." And by real, I don't mean you think it's a realistic game. I mean you think this could actually be the real world inside of your television. Missiles bombard the streets and footsteps creep up behind you, waiting to backstab you in the head with a knife.
In addition to the captivating world, the gameplay compliments everything flawlessly. Whether it be single-player, where the enemies are either relatively easy to kill, or a nightmare... where if you leave yourself uncovered for more than a second, you are a dead man. Or the multiplayer, where every match is different and the maps make for a great, diverse environment. Some are close-quarters, which make for some excellent brawls, while others are wide-open with brush and debri, making it a sniper's paradise.
Overall this game is nothing but flawless.
