About This Isn't Just Tower Defense
This Isn't Just Tower Defense is a tower-defense game where you place towers to fend off waves of thousands of enemies. Each defeated enemy gives you resources to upgrade your towers with more damage, faster shots and greater range. The pressure rises with every wave.
Power and production
Towers need power to fire. You generate it with solar fields and deliver it to towers using drones. Enemies also drop resources, which you process in factories to level up your towers. A balanced supply chain keeps your defense strong.
Towers and strategy
You can choose melee, ranged, single-target and area-damage towers, each suited to specific enemy classes. Combine tower types, unlock special towers and adapt your defense to face stronger waves.
Checkpoints and progress
Losing a wave sends you back to the last checkpoint, where you can try again without losing everything. You continue progressing step by step.
