Nexus Viridis

Connect the World, Shape Its Future

In Nexus Viridis, you are the unseen force guiding the planet’s cities toward a sustainable future. It is a real-time, single-player simulation-management game that challenges you to manage global resources by connecting cities across the world - one road at a time.

Each city produces and consumes three vital resources: Food, Water, and Electricity. When a city reaches abundance in all three, it becomes a beacon of hope, projecting green influence that heals the Earth. But if even one resource falls below demand, that city will turn to polluting alternatives, spreading red influence that harms the global environment.

Your mission? Balance the world.

Use a limited supply of roads to connect cities, share surplus resources, and prevent shortages before they escalate. Cities will automatically support each other — but only if you give them the means. Plan carefully: every connection counts, and every removed road shifts the fate of the planet.

But the world is unpredictable. Occasional crisis events can strike without warning, wiping out one type of resource in a city and tipping it instantly into scarcity. These moments test your network’s resilience — and your ability to adapt under pressure without sacrificing the planet’s wellbeing.

A global influence bar at the top of the screen reflects the state of the Earth. Let red dominate, and humanity succumbs to unchecked pollution. Fill it with green, and you’ll lead the world to a sustainable future.

The world wants to thrive — can you help it get there?
