Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
One tower. Endless waves. How far can your build take you?
Zenith Tower is an idle tower defense game about turning each run into lasting progress. Hold your ground against enemies approaching from every direction, choose upgrades during battle, and invest your coins in a stronger tower for the next run.
BUILD A TOWER THAT LASTS
Improve damage, health, attack speed, critical hits, and more with permanent Workshop upgrades. Balance firepower, survival, and coin earnings as you develop your build.
UNLOCK 12 ULTIMATE WEAPONS
Pull enemies together with Black Hole, strike with Chain Lightning, and unleash Smart Missiles. Golden Tower boosts coin drops, while Chrono Field slows enemies. Unlock and upgrade an arsenal that changes how you defend your core.
SHAPE YOUR CARD LOADOUT
Collect and upgrade cards, combine their effects, and unlock additional card slots as you progress. Experiment with different builds to find the right balance for your next run.
RESEARCH YOUR NEXT ADVANTAGE
Invest in Laboratory research for lasting bonuses. Unlock additional research slots and develop your tower over time.
PUSH INTO HARDER TIERS
Face stronger enemies, reach higher waves, and work toward new difficulty tiers. Refine your build and challenge your previous best.
EARN COINS WHILE AWAY
Return to offline coin earnings and put them toward your next upgrades. Research improves offline earning efficiency and duration.
Build, battle, upgrade, repeat.
