About This Game

High Voltage

Build your network. Generate power. Watch the island come to life.

High Voltage is a first-person 3D incremental simulation game about building and expanding your own power network across a beautiful island.

Start with a small source of electricity and gradually build your way toward a large, interconnected energy network. Place generators, connect power poles with cables, install substations and batteries, and deliver electricity to a growing city in the distance.

Every new connection brings you one step closer to a bigger and more efficient grid.

Start Small, Grow Bigger

Your journey begins with a simple power setup and limited resources.

Generate electricity, deliver it to the city, earn money, and reinvest your profits into better equipment and larger infrastructure. Each upgrade allows you to produce more power, expand farther across the island, and unlock new ways to grow your network.

What starts as a few generators and cables can eventually become a huge electrical grid stretching across the landscape.

The more you build, the more opportunities you unlock.

Build Your Own Power Network

Your electrical grid is yours to design.

Place generators where you want them, construct power poles, connect them using physical cables, add batteries and substations, and gradually expand into new parts of the island.

Plan how your infrastructure connects and make sure electricity can reach where it needs to go.

There is no single correct way to build your network. Expand at your own pace and create a system that works for you.

Generate and Sell Electricity

Producing power is at the heart of High Voltage.

Build different types of generators and take advantage of the environment around you. As your production increases, more electricity can be delivered to the city.

The power you successfully supply earns you money.

Use your income to purchase new equipment, improve existing infrastructure, increase the capacity of your network, and continue expanding.

More power means more income.

More income means more upgrades.

And more upgrades mean an even bigger grid.

Unlock New Technology

Growing your network is not only about placing more buildings.

Invest in new technologies to unlock better generators, improved infrastructure, larger energy storage, stronger power connections, new construction possibilities, and additional tools for managing your network.

Technology gradually changes what you are capable of building and gives you new ways to improve the efficiency of your operation.

Build your way from basic engineering to an advanced island-wide power system.

Watch the City Grow Brighter

The electricity you produce has a visible purpose.

Across the water sits a city that depends on the energy supplied by your network. As your production grows and more electricity reaches the mainland, the city increasingly comes to life.

Lights appear across buildings and infrastructure as your network becomes more powerful.

Watching the world react to your progress gives every new generator and connection a purpose beyond simply making a number go up.

Explore a Beautiful Nordic Island

High Voltage takes place on a realistic Nordic-inspired island filled with forests, rocky terrain, open landscapes, changing weather and scenic views.

Explore the island from a first-person perspective while deciding where your next piece of infrastructure should go.

Instead of managing your grid from a distant menu, you are physically there.

Walk between your generators.

Follow your cables across the landscape.

Stand beneath the turbines you built.

And watch your network spread across the island around you.

Build at Your Own Pace

High Voltage is designed around satisfying progression without constant pressure.

There are no armies to defeat and no race against the clock.

Take your time, explore the environment, experiment with different layouts, improve your infrastructure and enjoy watching your network become larger and more productive.

Whether you want to carefully organize every connection or simply keep expanding until the island is covered in power infrastructure, the choice is yours.

Grow Your Energy Business

Every successful expansion makes your operation more valuable.

Produce electricity, earn money, reinvest your profits and continue growing.

Upgrade your generators.

Increase your network capacity.

Unlock new technology.

Build larger infrastructure.

Expand into new areas.

And turn a small local power setup into a thriving energy business supplying an entire city.
