About this game

Area 81: Tower Defense is a tactical alien defense game where you build towers, control the battlefield, and protect your base from waves of evolving enemies.

Place machine guns, sniper towers, cannons, mines, shields and support defenses in the right positions. Every stage challenges you to think carefully, upgrade your towers, and stop the alien invasion before it reaches your base.

Use your drone to destroy environmental objects and open new tower spots. Expand your defense zone, create better paths, and build your own strategy instead of placing towers in fixed locations.

Fight across world-inspired regions, from the Nevada Desert to city streets, frozen lands and garden zones. Each region brings new layouts, new routes and stronger alien waves.

Features:

• Tactical tower defense gameplay
• One-handed mobile controls
• Offline gameplay
• Drone system to destroy objects and unlock new tower areas
• Multiple tower types with different uses
• Upgradeable defenses
• Evolving alien enemies
• Multiple world-themed regions
• Zoom support for easier battlefield control
• Increasing difficulty for strategy fans

If you enjoy tower defense, alien invasion games, base defense, tactical upgrades and offline strategy games, Area 81 is built for you.

Build your defense, expand your territory, upgrade your towers and stop the invasion.
Defend Area 81 with towers, your drone, upgrades and alien waves.
