About This Game

In Crystal Tower Defense you stop an endless amount of crystal-type enemies from reaching the portal to Earth. To achieve this goal you can build your own labyrinth using turrets and walls as well as selling obstacles on the map. You will need to stay alert since the enemies grow stronger the longer you defend the portal. Upgrade your turrets and alter the labyrinths layout to adapt to the new challenges.




Enemies will follow the path YOU create! This challenges you to experiment with different labyrinth layouts. The map, with its randomly generated obstacles, will tickle your strategic thinking every time you jump into a run. Remove map obstacles to open up new possibilities during a run and restructure your labyrinth to use each of your turrets to its full potential.




As you progress through the stages, you can unlock 10 turrets.
You can upgrade each turret's main stats in a run. The required gold is earned through destroying the enemies.
