TriDefense Free

By Kalio Ltda.

This app is only available on the App Store for iOS devices.


Gain control of Zorganto, fighting your way against the Bombdroids, with an arsenal of powerful towers.

TriDefense is a new tower defense game with a unique feature: modifiable terrain. This opens a whole new world of possible strategies to win the game.

Get engaged with the challenging missions, discover new strategies to fight the new water enemies along the classic air and ground ones, but most of all, have tons of fun!


Flood the land, or build over water, creating new paths for your enemies. Use it to explore new and unique strategies.

Place your towers freely in the battle field, and expect your enemies coming from virtually anywhere.

Beat your enemies in several missions, each one with unique objectives and a carefully planned terrain to challenge you. Enjoy each mission in the Rookie difficulty and get ready for the Expert!

Besides the ground and air enemies available in most tower defense games, fight the new water enemies. Look out for the smart enemies too.

Deploy your 18-strong tower arsenal, each one with multiple upgrade paths.

Use your ear to know where the enemies are coming from!

"This game is quite challenging due to the fact that attacks can come by land or by water, however it is interesting and fun. […] This is a great pass time and a good choice for tower defense fans."
