The original Kingdom Rush for the iPhone was a huge success, and now about a year later we are getting a sequel to this great game. If you haven’t played the first one in the series, Kingdom Rush, I recommend playing it to see if you like the series. They are both highly addictive tower defense games and Kingdom Rush is only $1 on the App Store right now and is still a great game that will give you a feel about how the second one will play out.
If you’re feeling adventurous or played the first one and loved it, you can pick up Kingdom Rush Frontiers for $2.99 on the App Store today. I highly recommend this game and I will be doing a full review of the game soon.
