This is not my first Tom Clancy game, I played the Splinter Cell and first Ghost Recon games. I have to say that I was impressed in some areas and disappointed in others.
Campaign: The campaign was very good with some cinematic experiences that I can remember after playing. The campaign can seem slow at times with not a lot of action but you have to remember this is a realistic game and there isn't always action 24/7 for our troops in the real battlefront. Weapon customaziation for the campaign is great and the whole squad based thing makes you feel attached to your teammate. Playing the story with friends is a great idea! Sound quality is amazing but graphics are better than most but not amazingly great.
Guerilla: Guerilla mode is a very good idea and can provide some fun when you play with friends. Guerilla mode is lacking creativity though and becomes repetitive. I would like to see challenges to do each round like MW3 does to keep it interesting. All in all guerilla is a nice add on to this game but it is probably the weakest game mode.
Multiplayer: Let's face it, this is what is going to make you want to buy this game. Multiplayer is amazingly great! Customaziation for the weapons and individual player is what makes multiplayer great. The maps make you work for kills and team coordination is a must or you will be slaughtered. There is always action to be found and a lot of creativity that makes you want to play it again and again just trying new things out. Once you find a combination that works out for you, you can dominate as long as your team/friends are on the same page.
Overall: This game is a great one with a strong campaign mediocre survival mode and an amazing multiplayer. This game is without a doubt a buy for tactical gamers and medium to hardcore shooter fans.
