You drop a single infected zombie into a crowded city street and watch the chaos unfold in real time. Infectonator is a strategy-meets-sandbox game where your goal is to wipe out entire populations by spreading a customizable virus across a map, one undead outbreak at a time. You click to release the infection, then upgrade your zombie horde between rounds to move faster, hit harder, and spread further before the timer runs out. Every city has its own layout and population density, so what worked in the quiet suburbs falls apart fast when you hit a packed downtown block. Think you can infect the whole world?
How to Play & Controls
- Left Click — drop the infection at your chosen spot on the map
- Mouse — hover to scout the map before you commit to a release point
- Left Click (menu) — select and purchase upgrades between rounds
- Left Click — activate special zombie units or power-ups mid-outbreak
Tips & Tricks
- Drop your infection near the center of the map so it spreads outward in all directions at once.
- Prioritize speed upgrades early so your zombies reach the edges before survivors can escape.
- Save coins for the special infected units — they carry your outbreak further than basic stat bumps ever will.
