As the first line of defense, you must bring down everything in front of you to ensure victory. You have been equipped with four guns, including an anti-aircraft gun to assist you in trouble.
Enemies are approaching closer and soon they will reach your base. Stop them by strategically placing from defense armies to turret towers in their way.
Use towers to build a labyrinth from entrance to exit. Each tower can be upgraded 4 times. With each wave, enemies will become stronger, so use money you earned to upgrade reasonably.
