Kingdom rush is a great game. I had played that game for several hours and now its next installment is here called the "Kingdom Rush Frontiers". Like the first part this game is also tower defense game and addictive too. The game has some more new island t defense. Some new abilities added to the game which makes it more fun. And the great thing is that this is modded and have all the characters unlocked.

Requirements :

1. Android 4.0 or above
2. ARMv7 compatible device
