Destroy the opponent by clicking on your cannon and drag it backward. Aim your arrow and let the cannon ball fly! Watch the clouds to judge the wind direction.
Defend the space carrier with a turret by gunning down as many enemy spaceships as possible. Get additional help by sending out carrier fighters of your own.
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.
We're under attack! Man the turret and shoot the creeps that are overwhelming the planet. Help is on the way but it'll take 100 more days. Can you survive till then?
