Night of the Idle Horde is an incremental zombie idle game where your horde marches forward on its own, tears through human defenses, infects survivors, and grows into an unstoppable plague.

Start with a single Shambler and watch the outbreak spread. Humans fight back with survivors, fighters, cops, soldiers, riot guards, and scientists who suppress infection. As the horde advances, you will earn Brains and Flesh, unlock new zombie types, break through blockers, equip powerful Vestiges, and push toward Outbreak Reset for permanent Mutation power.

Features:

• Command an automatic zombie horde that moves, attacks, and infects without constant clicking.
• Grow your swarm through infection, upgrades, and zombie type unlocks.
• Unlock zombie roles like Runners, Brutes, Spitters, Bloaters, and late-game Mutants.
• Break through defensive obstacles like Barricades, Spiked Barricades, Car Wrecks, Reinforced Gates, and Quarantine zones.
• Reset outbreaks after major milestones to claim Mutation Points and become stronger every run.
