Campaign

Campaign is the main storyline mode of Kingdom Rush, Kingdom Rush: Frontiers, Kingdom Rush: Origins, Kingdom Rush: Vengeance, and Kingdom Rush 5: Alliance.
==Description==
The player starts with 20 lives, and has to withstand a number of enemy waves based on the level. When the level is completed, stars will be awarded depending on the number of lives left:
* 18+ lives: 3 stars
* 6-17 lives: 2 stars
* 1-5 lives: 1 star
In the first three games, completing a level in Campaign mode with three stars will unlock that level's Heroic and Iron Challenges. In the next three games, the three-star requirement was dropped; completing a level in Campaign mode will unlock the Heroic and Iron Challenges.
==Levels==
The main storyline consists of 12 (Kingdom Rush), 15 (Frontiers and Origins), or 16 (Vengeance and Alliance) levels. Only the first levels (Southport, Hammerhold, Gray Ravens, Vez'nan's Tower, and Sea of Trees) are initially available; the other levels must be unlocked one by one by finishing the previous level. When the final level of the main campaign (The Dark Tower, Emberspike Depths, Shrine of Elynie, Denas's Castle, Hunger's Peak) is beaten, the Elite levels become accessible, some of which are not available on every game platform. Currently, Alliance has no Elite levels. Elite levels might be independent, unlocked immediately after the final normal level is beaten, or organized into mini-campaigns that are unlocked one by one:
