You place your towers along the path to prevent the enemies from getting to your base. If you are unfamiliar with Kingdom Rush, it’s a tower defense game on both Android and iOS that has won many awards. You can still get through the entire campaign with the characters you are given throughout the game. These purchasable characters are good, but in no way vital to the experience.

This isn’t inherently a bad thing though. There have always been some in-app purchases to obtain different heroes to help you in the game, and it doesn’t look like the price of them will be changing anytime soon. While the game has become free to play, this doesn’t mean that everything in the game has become free. With no notice and seemingly out of nowhere, the first tower defense title in the Kingdom Rush series had its price reduced from 99 cents to completely free. It looks like developer Ironhide Game Studio has decided to make Kingdom Rush free on Android.
