It is a pretty fun game, they only have the first level from World at War, but I'm hoping they add some more, also you can play over wi-fi, though I've never tried it.
I think a friend of mine tried it out and said it was pretty decent, although he thinks a lot of games are decent that normal humans would turn a blind eye towards lol
Yeah a friend of mine said it ruined the integrity of the game seeing as how they went with a fictional type of combat. I told him dude it's just a game let it go.
