A version for Android phones was released on the 26th of September 2013, available for $2.99 on the Google Play Store. Frontiers was finally released on flash on the 22nd of November 2013 and published on Armor Games. Like its predecessor, it has ranked over 18 million plays on Armor Games alone.

Kingdom Rush: Frontiers follows the formula of a typical tower-defense game. Placing towers on the side of a path to destroy enemies that appear in predetermined waves, the objective is to defeat all the waves before they reach the end of the path, using the towers and certain abilities. Letting too many enemies through results in a Game Over.
Frontiers continues the story that ended in Kingdom Rush. When the dark wizard Vez'nan was defeated at the end of the previous game, a new evil takes up his mantle and escapes into the wild frontiers to the south-east of the kingdom. The story unfolds gradually through information given at the start of each new level as you, the nameless General in the King's forces, lead your troops through vast desert, dense jungles and deep caverns to face off against the game's new villain, Lord Malagar, and whatever else is hiding in the shadows.
Game-play in Frontiers is no different to Kingdom Rush, allowing players of the previous game to fly straight into playing without needing to familiarize themselves with the set up. The game still includes the same tutorials and explains how things work clearly, so new players can learn quickly.
Starting a new game, first offers you a choice of difficulty. Casual, Normal and Veteran. The difficulty changes the Hit Points (or HP) of the enemies. The difficulty level can also be changed individually on each level. Each level is represented on a map of the Frontiers, which are briefed with a basic idea of what to expect before you can begin the level. There are three types of game modes. The default and main mode is Campaign, the story mode of the game. After this mode has been beaten with a 3-star rating, two new modes are unlocked; Heroic and Iron. These new modes offer different types of challenges, by changing the waves, enemies or towers available.
A completed level is awarded stars based on how successfully it has been played. The number of lives remaining determines how many stars are awarded, with three for almost none (18-20 lives remaining), two for an average play (17-6 remaining) and one for poor play (5-1 remaining). Failing to keep any lives will result in defeat. Both Heroic and Iron modes have only 1 life, and beating the modes award 1 star each.
Stars can then be used on Upgrades . Each upgrade requires between 1 and 4 stars and have a permanent effect on towers and spells. Upgrades can be bought and reset at any point during the game, allowing you to pick and choose the best upgrades for each level until you have enough Stars to buy all of them.
