Space Tower Defense
Defend your base from waves of futuristic enemies in Space Tower Defense, a classic and free online strategy game. Place and upgrade powerful towers along the path to destroy invaders before they reach your goal. It’s a tactical challenge you can play anytime.
How to Play
Enemy vehicles will advance along a set path. Click on a tower type from the menu, then click on a green build site along the path to place it.
Each enemy you destroy earns you energy, which you can use to build more towers or upgrade existing ones. Click on a placed tower to see its upgrade options.
Different towers have different strengths—some are fast, some do splash damage, and some slow enemies down. Create a balanced defense to survive all the waves and protect your base.
