Great multiplayer, but in the year we're in now, I dont know if I can say so.
Multiplayer: The multiplayer is about the biggest part of Modern Warfare 2. So it really goes like this, get titles, emblems, killstreak rewards, weapons, and all the other stuff you can unlock, especially the leveling system. Now, I've heard millions of "I can own you"'s and, "I'm Prestige 10"'s and all that stuff. COD MW2 can get a bit competitive sometimes.. and I mean they get into real fights over the internet.. I mean, seriously? Besides that, it's real fun! Kill people, level up get weapons, titles, and emblems, I mean, sounds fun right? Some people over Xbox Live or PSN take this stuff to seriously. Okay, okay, I'll stop trolling about that but, yeah. There's a lot of levels to explore too! But I don't reccomend exploring though... You won't get a good Kill/Death ratio. Rating 8/10 because of hackers and annoying people takes 2 off.
Campaign: Some people say it was too short, I say it was just fine. Go play as about 4 different characters in a short amount of missions. I mean it was short compared to other Call of Duty's but it was fine as a starter of in Call of Duty. Not much to talk about it, don't want to spoil anything. Rating 8/10
Special Ops: Competitve, just how I like it. Playing special ops with my friends online is loads of fun. There is a bunch of missions where it's testing your highest amount of skill in one point. I don't have alot to say about this mode either, but I spent a lot of time on this mode. Rating 9.5/10 Awesome!
Sum Up: This game is a must get!
And if you are thinking about Black Ops too it's also great!
