About Exo TD

Exo TD is a tower defense game set in fully 3D space. You command your planet’s defenses, using resources to build turrets, shields, orbital defenses and other installations while maintaining your Planetary Shields against invading forces and their flagship bosses.

Defend your planet

In standard mode, invasion forces arrive periodically in waves. Each wave brings increasingly difficult AI ships with new tactics, strategies and reactive combat abilities. If an invasion penetrates your Planetary Shields, the planet and all its defenses are lost to the enemy.

Upgrade your defenses

Destroyed enemy ships often yield collectible drone scrap. You can use these resources to upgrade turrets into newer, more powerful models and improve their defensive capabilities against the escalating threats.
