Call of Duty, Modern Warfare... among the very best. One of my favorite games of all time.
I was introduced to the game as a team building game at work. I started playing the game on the PC first. I found that when I got home after work, I wanted to play COD4 so I picked up a copy for my 360. I was very lucky in that I had just completed my new home theater.
When I fired up the game, I made sure the sound was up and sub on high. The environment was awesome with surround sound. The game does a great job of giving audio clues as to where your team and enemies are. You can hear people sneaking up on you (as long as they don't have the dead silence perk). Can get pretty intense if you allow the game to immerse you in it's environment.
I like the weapons available, my favorite is the sniper/claymore combination the best, but having a SAW to mow down enemies is a great alternative. I like the ground war multiplayer the best because there are plenty of people playing at the same time.
The single player mode is great, my favorite part is the overhead mission with the big sky gun. I wish they would have developed that aspect into a couple more missions.
I think playing on the 360 is a bit tougher in terms of game control, but after playing for awhile, the 360 controls are no problem at all compared to the keyboard on the PC version.
The main reason I like this game is because you can login, play a couple rounds and logout.
I would recommend this game to anyone that enjoys the genre of war and battle.
