Although the CoD franchise has made it a long way, this game falls extremely short of 360 and ps3 versions.
To start I will say that the game controls are customizable and nice, and fun using the nunchuck and wiimote. Expect to be addicted because even if you are terrible you most likely will come back for more.
I play CoD pro and have played pro for almost 8 years. What I am going to tell you is the truth, and not a reason for you to buy the game unnecessarily so that experienced players have noobs to beat up on. I'll start by explaining what this game has and what WaW includes for 360 and Ps3.
This game is missing alot.
-Zombie Mode...HUGE LOSS!
-Unlockable Challenges...Humiliation...Elite... These were by far the most fun challenges that the other versions had to offer. (Kill 2 players or more using 1 Bouncing Betty)
-Reconnaissance perk...Huge considering that it made people think more than twice before prestiging. (ability to see dogs and artillery on radar)
-Tanks and vehicle perks...
-4 maps (more considering that downloadble maps are already out for other ports)
-CTF, Search and Destroy, Sabotage, and other game modes...
The guns are the same but I can assure you that many of them work terribly...
MP40 will be you gun of choice considering it works the best. 80% of people prefer it simply because it is hard to shoot the ones that have but its easy for them to shoot you. Sniping is next to worthless. I consider it worthless because I am upset if I fail to hit a 30-5 K/D every game. If you like getting owned for some strange reason than sniping would be the right method for you. Machine guns are so-so however they are no match for and mp40 if any reasonable distance is achieved. If you waste your time with a shotgun, your stats will soon prove it.
Cheating occurs alot in this port, I MEAN ALOT. Expect to get stand-byed or glitched 1 out of every 3 games.
What do I mean by Stand-by? You and your team will consistently walk into walls while the host runs around and owns you.
What do I mean by Glitching? People will be under the ground, above building that you normally can't get above, and in buildings that you normally can't get in. They can see and shoot you, but you cant see them.
There is also a horrible flaw where people can see your shadow on a second floor, when you are on the first. So if I'm on the second floor and I see a shadow at my feet, I can simply jump down and own them. That is not only unrealistic, but it is also impossible.
For some strange reason, I will be owning people and I will get lagged out with a message that claims "Server Connection Timed Out." I would believe that this isn't a cheat normally, however it only happens when I am destroying people.
Finally, Treyarch is a horrible game developer that has no care for their customers. 360 owners had major gripes about this game and they fixed 15% at best. Wii owners got NO LOVE, and are dealing with the same horrific problems since the beginning. They will eventually crash completely since this is another epic failure after CoD 3. Once people realize that they are working on their next project while leaving us "in the dark" with a brutal failure on this one, all will be done for them. If Activision has any sense they won't let this happen. You post a message on their website and they come up with this; "If you don't threaten us, we will consider your claim and fix the problem." First of all they treat everyone like a little kid that is to be rewarded with candy. Secondly they fail to fix anything, and if you don't believe me try them and you will soon see that I am FAR from lying.
Bottom Line:
If you like a game that does NOT function correctly and shots must be lead inches on your screen from 5 feet away, then this joke of a game is for you. If you like anything realistic, that does not play like paintball, then wait for a real game and hope that Modern Warfare decides to make a game for the wii. I could only hope that the wii port gets this lucky.
