I would also add that weapon balance is terrible. Akimbo has been removed but SMG s have replaced it.

Thats why other weapon classes are allmost useless.

I loved to play in previous CODs with assault weapons, but here just hairdryers (SMGs) are good to stay alive :D

Sniper is deadly but the aim is terrible.

Other thing that I hate in game is the matchmaking, now you cant even edit the cfg to get more latency bars to see it more accurate. Sometimes it shows full green bars, but i think that sometimes i have 150-200 ms ping, and thats alot. So its only a decoration, problably it will be less bars above 200ms no wonder that SMGs are shooting like hairdyer.

And now i read so funny comments like "ahh this game i good....etc." But none says why is good or bad. Comparing to other CODs. 
But as wee all know in latest CODs that the games are not made for skilled players anymore. That why they made it easy to kill no need for precise aim, just shoot and make every less skilled player happy.

I never played the SP so i dont know how good or bad is it.

But MP is terrible gamespot gave too high rating for game i would give 6,0
