Mob Factory is a tower defense and automation game for the lazy adventurer. Smelt down enemy loot into turrets & factories to automate an ever-expanding dungeon from the comfort of your tower. Defend Build an interconnected factory to turn mobs into resources, buy islands, craft new spawners, and more. As you acquire new materials from new enemies, upgrade your assembly lines with new technology to make it increasingly efficient. Defend against waves of enemies that will become the fuel for your factories. Shape the path they take to maximize your damage output. Upgrade Use enemy drops to brew potions. Melvin the Wizard will use them to upgrade your factories! Spend resources to raise new islands. New islands contain undiscovered spawner types, new resources, and more area to expand your base.
