the new maps are pretty fun, deff worth the money if you play the game often, crash is a little anoying if you like sniping off of the 3 story as danger close noobtubes tend to get spammed towards it D:
According to steam (so dunno if it's different from XBox) there's 5 maps in the package and it goes up to £12 if you don't preorded at £10.79, but In my mind that's still pretty poor show from Infinity Ward. First they give us the fail of IWNet, then make us pay for only a few extra maps? They used to come free in patches for all previous ones. This should be free to make up for not giving us dedicated servers!
I really don't mind IWNet. I rarely have problems with it. Although I don't like that you get a random map. I really hate some maps and would prefer a choice.
