Gaia 2200

Gaia 2200 is a tower defense game set on Earth 200 years after humanity’s actions have badly damaged the planet. You become captain of the GAIA Project, a human effort to protect Earth, and fight alongside your partners to save the world.

Choose and cast spells

You select 7 spells from a pool of 30. Match spell cards and choose when to cast them, including which levels of each spell to use, to maximize damage while protecting the tower.

Defend with your heroes

You choose spells to suit the monsters’ types and formations, and move heroes quickly between attack and defense. Success depends on both your spell combinations and your timing.
