The Heroic Challenge is a challenge for good players.
DescriptionIn order to unlock the Heroic Challenge on a level, the player must have got all three Stars/points for the Campaign mode of that level. The player only has one life and has to withstand six large waves of enemies.
Upgrade paths have a set limit on each challenge, increasing for higher levels. In the first ten levels in Kingdom Rush and the first four levels in Kingdom Rush: Frontiers, heroes are also not available. Completion of the challenge is rewarded with a Star; in addition, the flag of the respective area on the campaign mode map will gain golden wings.
In Kingdom Rush: Vengeance, there is no limit to available upgrades or the availability of a Hero. No points are awarded upon its completion, however, like all levels completed in the game, gems are awarded at the end.
