About this game Read the full description

//Select a level, and aim your tower's artillery towards incoming enemies. BOOM! Grab any precious resources the enemies drop.

//The tower will inevitably fall. Under your command, it will rise even stronger. Fortify your tower with weapons and upgrades.

//Research new and increasingly powerful tech.

//Defend the Bastion until the end. You and your weapons research program are the last line of defense against the machine army. There's no telling if this reckless operation will allow Humanity to survive. What will happen when the horde becomes insurmountable?
