Greater than MW2, Less frustration!
Haven't played much about it but I hope its great.
Multiplayer
For starters, this game is not for noobs! This game is for people who really care about objectives. Capture points, destroy objectives, defend objectives!
You have to really get your head in the game and don't go for kills, its just gbeing disrespectful, don't try to "quick scope" actually snipe, don't try noob tubing across the map, don't run around tactical knifing, melee when have to.
Guns are great, it is just so realistic, Snipers are heck of a lot better than Modern Warfare 2's! You can be a recon where you can give support for your teammates and snipe from fire for support fire. Or a medic, help injured teammates providing them with med kits, also when they die, you can revive them back to life. The job of Assault is to fight close range with big assault rifles ready to squash their faces, they provide boxes of ammunition and very good at far range fighters too. The job of engineer can take down any vehicles, aircraft and supplied with a silenced sub machine gun, you are also equipped with a power tool to fix back the vehicle to its proper significance.
Maps
Maps are as big as islands, they are all perfect, well balanced and just prefect, they really make you intense like you are actually fighting in war, just always remember to be in a squad to spawn with your teammates, because spawning back at base is very tiring.
Just try out the game for yourself, use your head on how to kill the enemy, this game is very realistic so be serious.
