The campaign sucked and for the most part the MP sucked. It took forever to get the lag comp fixed, Support Package was imbalanced and the maps weren't that good. I thought the DLC maps sucked and only played them because I had them paid for by buying the Hardened Edition.
I do like the gun selection...a lot. I can use almost any of the guns and enjoy myself. It got tiring seeing everyone use the ACR, MP7 and PP90M1 though. I don't play often, infact I took a 4 month break until just this week when I decided to shoot people and it's not bad. It's the only CoD I have that isnt hacked to pieces. I just really like playing Domination as long as I get 1-2 people who know how to play on my team. I get mad and have to turn my mic on to give people "guidance" sometimes but if my team can't win I just go for kills instead of playing the flags.
Play Far Cry 3, it's better, and has a better MP.
I was always a Medal of Honor man...well, the old ones for the PSX, lol. I'm not really into FPS-War games, much. unless it has to do with aliens, like Resistance.
