About
This is a sci-fi idle tower defense game unlike anything you’ve ever seen!
AI machines have launched a counterattack against humanity, pushing mankind to the brink of extinction. With every last resource, humans built the strongest fortress ever created. You have been appointed as the final commander of humanity inside the fortress. Build and command powerful mechs, fight back against the invading machine legion, and reclaim the homeland humanity once lost.
Upgrade and promote every turret in your defensive fortress to attack the endless waves of mechanical enemies and stop them from breaching the city. Summon heroes from all fronts, send them beyond the walls to fight the enemy, choose the right skill combinations, and strike at the perfect moment to deliver a decisive blow. As the commander, you will engage in a battle of power and strategy against alien machines on this blue planet.
Commander, lead humanity and take back our home!
