Very interesting game for strategists and thinkers in general those who love the game of logic and towers. Today you will guard the portal of enemy forces and for this you will have a great opportunity to elevate the protective towers. Before installing the tower read, in what way it attacks the enemy, may slow, can jam, might just shoot with more damage, and can fire at air targets very effectively. Each tower must be installed with the mind that none of the contenders failed.
