If you're like me and put this one off based upon the mention of toxic gas, do yourself a favor and play this campaign.
Easily one of my favorites and well worth a five star rating.
The airstrike system was highly unique. Sitting back and listening for the sound of spawning tanks, blasting them into oblivion was a real treat.
The added voice acting was pretty good. I've played a good thirty+ maps and I've seen some pretty bottom of the barrel attempts at voice acting. It was nice not to hear someone with a lisp wheezing into a microphone and sixteen times normal volume. Or in some cases, whispering inaudibly into a microphone necessary objectives. Being able to hear what you need to do is kind of important and this map hit the nail on the head.
Fun for the whole family. I completed this map on advanced with two bots.
