If anyone played through the first chapter and enjoyed it, and was considering buying the second chapter, buy it. The second chapter was a lot more fun in my opinion. There's plenty of extra ships, aircrafts, submarines, plus more abilities. Even the story was better. The missions were harder and took a lot more strategy. One of the levels was ridiculously hard. So if people were holding on to their $1.99 to see if the second chapter was worth it, fear no more. It's definitely worth the cash.
