Zombie Idle Defense

Hold the line against the undead horde in Zombie Idle Defense, the strategic idle shooter where preparation meets pandemonium! As the last bastion of humanity, you must engineer an impenetrable fortress while managing automated defenses that blast zombies even when you're offline. Return to collect resources, upgrade arsenals, and push deeper into the apocalypse.

The defense grid allows complex tower synergies: machine guns shred basic walkers, flamethrowers melt armored brutes, Tesla coils chain-lightning through crowds, and cryo-towers slow incoming hordes for maximum damage exposure. Research the tech tree to unlock orbital strikes, minefields, and autonomous drone swarms. Prestige systems reset progress with powerful permanent bonuses, enabling infinite advancement.

Face evolving threats across 50 apocalyptic zones: sprinter zombies that dodge projectiles, exploders that detonate on death, and colossal boss mutations requiring coordinated defensive strategies. The "Horde Mode" endless survival tests your build's limits against infinite waves. Even while idle, your defenses generate cash and materials—strategic offline planning matters as much as active play. With its dark comic aesthetic, satisfying impact feedback, and genuine strategic depth, this is the definitive zombie defense experience.
