In eHUB cities – Blackout, you take on the roles of Jan and Angela, who are each confronted with a large-scale power outage. Fortunately, your home is an eHUB: a smart, self-sufficient building that serves as an energy hub for the neighborhood in times of crisis.

Keep an eye on your power consumption while you cook, heat your home, or charge your devices. But beware—the eHUB's resources are limited, and your neighbors want their fair share. Or will you deny them?

Will you overcome the crisis?

Make impactful decisions, manage limited energy resources, and navigate interpersonal dilemmas. Your actions affect not only your personal goals, but your relationships, health, and the well-being of those around you. Will you make it through the blackout — and who will you become along the way?

Two characters. Two blackouts. Countless stories.

Immerse yourself in the lives of two unique characters, each facing a different crisis and personal challenges. Only one thing reoccurs: the blackout.

Level 1: Jan – The Desperate Entrepreneur

You have one last chance to save your company, but you have hardly any time left to prepare the perfect presentation. Then a snowstorm hits and cuts the power. Your eHUB's resources are almost depleted. Now, you must decide: will you help your neighbors, or is your own future more important?

Level 2: Angela – The Suspicious Hacker

For no apparent reason, the power grid fails. Seconds before the power outage, the lights in your eHUB flicker briefly. Coincidence – or is there more to it? You have to get to the bottom of it. If only your wife Kathrin weren't so determined to involve you in her own problems.

Every decision counts

Shape your own story by making decisions in interactive environments and in-depth conversations. Every choice matters – for your well-being and that of others.

Potential for Conflict
