About This Isn't Just Tower Defense
Place Towers, Defeat Enemies, Stack Upgrades
Strategically place your towers to fend off massive waves of thousands of enemies at once. Every defeated enemy grants resources you can use to endlessly upgrade your towers—more damage, faster shots, greater range. The pressure increases with every wave!
Energy & Production
Towers need power to fire—generate it using massive solar fields and deliver it to your towers via drones. Enemies drop resources that must be processed in various factories to level up your towers. Only a well-balanced supply chain will keep your defense strong.
Versatile Towers for Every Situation
Choose from melee, ranged, single-target, or area damage towers—each type excels against specific enemy classes. Combine them wisely, unlock special towers, and find your perfect defense strategy. Only those who adapt will survive the strongest waves.
No Game Over – Only Progress
This isn’t your typical tower defense! If you lose a wave, you’ll simply jump back to the last checkpoint—ready to try again. You never lose everything; instead, you push forward step by step. Every setback is just another step toward victory.
