The Vectoids are on the move. Can you stop them? The aim of the game is to eliminate the Vectoid threat before they reach the end of the path. You do this by constructing towers along the path to attack oncoming Vectoids. Success is not based solely on the types of tower you select, but where you place them and what upgrade and bonus options you take. Play Fun and Funny Games at Fungames.com. Best Vector TD games.
