Balloon Invasion

You are the commander of the anti-air defense in the area. The enemy is invading from the open sea with enormous battle groups of bomb-armed balloons.
You can establish defense structures and call air raids to push the enemy back into the sea. Win battles, gain experience, level up and use your commander points to gain access to upgrades and various weapons.
The fate of your country is in your hands. Good luck, Commander!
