You get what you pay for, nothing more nothing less.
It is a rather good addon for such a low price.
A couple of new maps and some new vehicles.
I missed some new weaponry though since this doesnt affect the original Battlefield in any way.
Since its already used graphics and sound I cant really give it a higher grade but all in all its a fun addition.
But I must say I enjoyed this addon better than the previous one since you finaly get to fight inside the american boarders. Very amusing to get a chance to beat them in their home field.
Nothing fancy, but nothing bad either.
A good spent ten dollars in my mind.
