A mixed feelings.
It fixes some of the problem encounter by COD4 multiplayer like too small map, more ranks, class creations, perks, weaponaries and prestige for lengthening the muliplayer game experiences of players.
The use of tanks in muliplayer is real cool, however only a few maps have the uses of tanks. And by the way, there was only 11-13 maps in muliplayers which is not enough.
Singleplayer and co-op, well it's pretty solid, however I can't even find more than 4 servers in co-op and 3 of them are pings too high, so if you want to buy this for co-op, think again.
Zombie mode is real dumb, you will die anyway, no matter you die in level 1 or 10. You can't escapethe small house and just wait for death. Boring isn't?
AI is also a major problem in this game. Many of them can't even see when you are JUST next to them. I had a time that I knifed/bayoneted 5 persons in a row before they saw and fired at me, you can see what their intelligence are like.
They can shoot you 300 meters away but can't even see you 1 meter near him, ridculous.
There are also too many grenades thrown by enemies. Know what, about 70% of my death in the game are caused by enemy grenades in this game. Especially in small streets or treches or jungles where you can hardly move.
Banzai charges by the japanese is really cool, however the charges are limited to several persons only, which makes the charges like sucide rather than a real counter-attacks.
The rush of the nazi german makes them looks stupid. They hardly take cover and just stand there waiting to get shoot or rush front/ back like the japs.
Anyway it's still a good game.
