A single infected cell pulses on your screen, and one tap sends it splitting into a chain reaction that races across the map. In Viral Outbreak online you spread your strain through a packed grid of hosts, click to release infection bursts, and watch the contagion ripple outward while a counter ticks down. Every cell you tap detonates into more, so timing your spread to catch dense clusters is how you clear each stage before the limit hits. You drag to aim where the next wave lands and chain combos to push your infection rate higher and higher. Think you can take over the whole grid?
How to Play & Controls
- Left Click / Tap to release an infection burst
- Drag to aim and position your next spread

- R to restart the current level
Tips & Tricks
- Target the densest clusters first to set off the biggest chain reactions.
- Save your stored burst for tight corners where cells are hard to reach.
- Watch the timer and clear edge cells early before they spread out of range.
