Echo Pandemic

Earth needs antibodies. You are one of them.

The Clamor came down from the sky and took the towns. Their bodies were never built for this world, and you carry the one thing they cannot survive: a virus.

Infect alien hosts by night. Engineer new strains by day. Stay ahead of vaccines, quarantine efforts, and increasingly dangerous enemies as you fight your way from isolated villages to the Clamor mothership.

Your weapon is a disease

One bite seeds an outbreak.

Design your virus by balancing transmission, symptoms, and lethality. Spread it through contact, contamination, or the air itself. Delay symptoms to reach critical mass. Increase lethality to thin enemy ranks. Adapt your strategy as the Clamor develops new countermeasures.

The outbreak spreads without you

Every infected host becomes a carrier. Diseases spread through the population while you hide, mutate your strain, and prepare for the next night. Multiple outbreaks can exist at once, creating a web of infections that evolves across the entire campaign.

Hunt by echolocation

You are a bat, and you see the world through sound.

Your chirps sketch the environment into existence before it fades back into darkness. Scan pulses reveal infection status in the only color the world allows itself. Every night becomes a balance between information and exposure.

Sound helps you see. Sound also gives away your position.

Stay hidden in vents, rafters, and dark corners while you search for new hosts. If the Clamor spots you, patrols respond. Soldiers mobilize. Cybernetic hounds begin the hunt.
