## What is One Tower?

One tower stands between the core and an endless alien invasion. In this idle tower defense strategy game, every run is a new chance to upgrade, adapt, and push farther.

Combat fires automatically while you choose the upgrades that keep your defense alive. Spend cash during each run, balance attack, defense, and utility, then turn every defeat into permanent power.

BUILD A STRONGER DEFENSE
• Increase damage, attack speed, range, critical chance, health, regeneration, and more
• Adapt as fast enemies, specialized threats, elites, and bosses close in
• Push through endless waves and unlock harder tiers

GROW BETWEEN RUNS
• Invest coins in permanent Workshop upgrades
• Run research that keeps progressing while you are away
• Collect and master Relics that reshape your strategy
• Unlock Drones and Special Weapons with distinct effects

MAKE EVERY RUN COUNT
Automated combat keeps the action moving, but your choices decide how long the tower survives. Chase new best waves, complete missions and milestones, refine your build, and return stronger.

How long can your final defense hold?
