The setting of kingdom tower defense is a medieval fantasy setting. It is an online game that emphasizes building and defending towers. The tower defense game has empty slots around it on each level where players can put up towers. Players in the game have four tower options: mage, barracks, and artillery, or if you like D&D reference, sorceress, fighters, rangers, and gunslingers.
The player constructs a new tower at the beginning of the game using resources provided in the game. The tower has to kill all the enemies before they get to the defense line, or the game is lost. The tower defense is augmented by heroes and spells that the player receives in the game. To upgrade towers, players use the money generated by defeating and eliminating enemies.
Upgraded towers are more effective. Initiating early enemy attacks is another way to generate more money for the tower upgrades. Kingdom tower defense has 18 levels and a variety of 48 enemies that you will battle in the game. For every level completed for the first time, a player earns 1 to 3 stars. The stars are used to unlock passive upgrades that help with increasing the potency of tower spells.
When you complete the campaign mode and have 18 or more lives, you can unlock the heroic and iron challenge mode. The two modes are advanced, and upon completing them, they award the player with one star each. The two modes have one life each, and if an enemy makes it to the defense line, the level is failed.
The latest update of the game comes with a hero's room and a shop. In the shop, a player can buy extra coins used for tower upgrades and dynamite that can be bought by winning gems in the battles.
