Kingdom Rush 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.
Kingdom Rush expands on the usual set up by using a limited number of tower types, whilst introducing individual units that engage enemies on the path and including bosses. As levels progress new towers and further upgrades are unlocked. Heroes are used as unique units that can be directed around the level. Heroes have special moves that increase in strength as they gain experience through a level, and will regenerate if defeated.
The story of Kingdom Rush unfolds as each level is started, with a basic introduction to the stage written as instructions to you, the nameless General in the King's forces. From the first stage, a small town on the coast under attack by roaming outlaws, the game follows a route through the Kingdom and beyond, fighting off an invading force led by the main antagonist; and ultimately final boss; the dark wizard Vez'nan.
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 Kingdom, where 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.
An in-game encyclopedia records all new information as it is revealed in the game, such as tower and enemy statistics. It also has several basic Tips and Tricks and a link to Strategy Guides provided by Ironhide Studios themselves (videos of the levels being completed).
