For example, on Normal difficulty, the first Forest Troll always spawns with 4000 HP regardless of wave the next wave it will have 4080 HP, then 4162, 4245, 4330. Waves in Endless mode come in a much faster pace than in Campaign mode, with the first wave bubbles appearing only a few seconds after the previous wave is called and lasting only a few seconds themselves before the enemies are spawned.įor the first time an enemy spawns in an Endless stage, they always have their base stats, after which their HP and damage will start to grow equal to 2% of their current respective stats. This adds an extra aspect of maintaining a fine balance of towers. However, enemies do appear to spawn in such a way that will best take advantage of your choice of towers, for instance spawning flying enemies on paths with only Barracks and Artillery, or spawning enemies with high defense to take on Archers. The waves in Endless Challenge are procedurally generated from a pool of enemies, so no matter how many times you play, there is no pattern to which path they will appear on, or what enemies will be spawned with the exception of minibosses that spawn every 10 waves in their respective stages. Unlike the Heroic Challenge or Iron Challenge there is no limit on what towers can be placed and Heroes are fully available. The player starts with 10 lives and has to withstand an endless number of waves of ever-increasing numbers of enemies. Unlike other modes, the Endless Challenge is played on its own levels, dedicated to it, distinct from all Campaign levels - a normal Campaign stage cannot be played on Endless and vice versa.
An Endless Challenge is unlocked once players have beaten the last stage of its terrain in the main Campaign.
