## What is Voltspire?

One tesla coil tower. Endless robot swarms. Permanent upgrades. No pay-to-win grind.

Voltspire is an incremental tower defense game where your Spire fights on its own and every run makes the next one go further. No forced ads, nothing essential behind a paywall, and it plays fully offline.

HOW IT WORKS
Enemies drop Charge, which you spend mid-run on damage, fire rate, health and defenses. When the Spire falls, you keep the Scrap you banked and turn it into permanent upgrades:
• Coilworks: instant upgrades
• Blueprints: research that runs in real time
• Chips and Components to collect
• Overdrive weapons that clear the screen
Then you dive back in, stronger than before.

GOALS
Climb 21 Voltages of escalating difficulty, chase wave Milestones and complete daily and weekly Missions. Let the auto-battle play itself, or dig into builds: tank, glass cannon, control or economy farming.

FAIR BY DESIGN
• No forced ads
• Nothing essential behind a paywall
• Plays fully offline, no internet needed
• No fake offline earnings: a closed game pauses exactly where you left it

If you like idle games, incremental games and single-tower defense, Voltspire is built for you. How high can your Spire climb?
