Transform empty wastelands into a fortress, the bastion that will hold the empire. Build turrets, guns and place units in this tower defense game. Enemies will come in waves, called or not, so ensure each road has enough force to stop their incoming. Give the troops an awe-inspiring cause to fight for. Use the Mouse left-click to distribute the towers and guards, investing the money gathered for that. Once every stage is cleaned up, with no more enemies or bosses invading for the moment, apply the upgrades. Make weapons and chances of survival greater, manage the impenetrable and ever-lasting bastion.
