The object of the this strategy game is to stop the evil "creeps" (in this case random objects) from getting to their destination. In order to do this, you have been equipped with weapons of suvh devistating effect that the creeps should simply give up now.

You are, however limited by how much cash you have to spend on development and upgrading your equipment. Saving up for bigger towers and upgrades will allow you to pack a heavier punch.

At the end of each level, interest is added to your cash reserves, so timing when to put a new tower down can make a lot of difference!
