Mixed feelings about it.
Pros:
Epic story (still working on it but its already epic)
More multiplayer modes.
Spec Ops is back!
New Weapons
Cons:
Looks and feels a lot like MW2 (but all the COD's are pretty much the same thing so I don't understand what the fuss is about)
There's lag in the story mode (for me anyway, don't know about anyone else)
Multiplayer Gameplay needs some patches
No Zombies
So overall, I like this game so far. I'm kinda surprised there is such low ratings about it. Multiplayer is always the same in pretty much every COD game. They have different modes sometimes and thats it but it's always kinda the same thing. I will admit though, its basically MW2 over again with a few tweaks.
The story mode is the thing I always look up too. Its not always about the multiplayer. And so far, the story is epic! It kept me playing to the point as where I almost didn't sleep!
I'm gonna be honest here, I HATED Black Ops. The art style was horrible, the multiplayer was not as good but it did have some good weapons. The story mode did not make any sense. After playing MW2, what I wanted to see was what happened after MW2 and Black Ops certainly did not do that. Instead they gave me a campaign with a story that is totally off what I wanted to see. The only thing good about it was zombies.
Spec Ops I've only played a couple missions but it's pretty interesting. And still has co-op ones so thats still good.
Overall, in my opinion, MW3 is good and I'm sticking with it. I really like the campaign and spec ops. Multiplayer is good but it needs some tweaks to make it better. So I would recommend this but if you don't like it, thats fine. I respect your opinions!
