Aliens V Heroes Java Game

Your mission is to help the aliens on their quest to abduct as many puny earthlings for the mothership as they can, but watch out! There are tiny, neighbourhood heroes and trigger-happy military units gunning for your flying saucers, and earthling technology just gets better and better! Of course, you'll be able to upgrade your ships as well, but will that be enough? Can you enslave all those earthlings? Wait 'til they pull out the big guns!
