You click a single zombie into a crowd and watch the chaos riple outward — that's the sick satisfaction at the heart of Infectonator 2, a strategy-sim where you engineer global zombie outbreaks one city at a time. You drop infected units onto a world map, then sit back and watch (or nudge) the spread as survivors scramble and your horde multiplies. Between rounds you spend coins on upgrades — faster infection rates, stronger zombie types, special units that tear through resistance — and then you unleash it all over again on the next target. It's equal parts idle game and tactical sandbox, and once you see a whole city go dark in seconds, you'll want to do it to every dot on the map. Think you can infect the whole world before time runs out?
How to Play & Controls
- Left Click — drop your infection payload onto the map or select upgrades in the menu
- Mouse — hover over cities on the world map to preview population and difficulty
- Left Click (upgrade screen) — purchase zombie upgrades and unlock new infected unit types
- Left Click (in-round) — deploy special zombie units mid-outbreak to push stuborn pockets of survivors
Tips & Tricks
- Spend your early coins on infection speed upgrades — raw spread beats raw power at the start.
- Target smaller towns first to farm coins quickly before hitting dense cities with high resistance.
- Santa and other special units have cooldowns, so drop them on military clusters, not open crowds.
