Aliens have infiltrated the naval command ship. You are the captain and you'll go down with your ship. The question is how many aliens will you take down with you?
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.
Kill all zombies before they reach the top of the canyon and wreak havoc on the citizens of Zombville. Kill them all, make money, upgrade your weapon and buy power-ups. Good luck!
