Voltspire: Idle Tower Defense is an addictive idle strategy game where every run makes you stronger. Defend your Spire against relentless waves of enemies, collect valuable Scrap, unlock powerful upgrades, and climb ever higher in an endless tower-defense adventure with limitless progression.
Tap Battle to begin a run. Your Spire attacks automatically, while you spend Charge on powerful battle upgrades as it is generated. When your Spire is destroyed, use your banked Scrap and Gems to purchase permanent upgrades before starting a new, stronger run. Push deeper into the tower to unlock new Voltages, Overdrives, and advanced systems that expand your strategy.
