Revenant Earth

The world is ruined by the climate crisis. As the last human on Earth, you have one task: bring the planet back alive. Master nature, technology and weather to build an entire ecosystem in a living, simulated pixel-art world.

Genre: Adventure / Strategy

Platform: Browser

Status: In development :)

Based on deep climate research, Revenant Earth simulates atmosphere, weather, plant life and soil. Eroded soil dries fast in the overheated atmosphere. Plant roots can stabilise the erosion, but they need nutrients. They can be recycled from the ancient dried trees, but timing is crucial - wait too long and the torrential rains wash the nutrients away. Strike a delicate balance between growth and water consumption. You have technology to assist you, but here, power isn't easy to come by.

Overcome all these challenges - and you can sustain an ecosystem to build a new home for humanity! 

Explore the environment. Find a spot of fertile soil to plant Earth's first new generation of life. Start small, with grasses and shrubs, before moving up to trees that capture immense amounts of CO2 - and require immense amounts of water. 

Until you tame them, the harsh elements await every opportunity to take back your reclaimed land. Neglect an overstretched water supply and erosion may slowly creep back under the dry roots of your plants. Lower the global temperature and calm the weather as you progress.

In the near future, the climate crisis reaches its peak. Earth’s resources are depleted, while droughts, flood and conflict make the planet uninhabitable. What remains of humanity escapes into space to giant orbital stations.

Decades later, the spacefaring nations unite to form the Environmental Restoration Agency. Their goal: to restore the Earth’s ecosystem.

As one of the ERA agents, you return to the surface to explore the ruins, clean up the environment, and reintroduce life into the dying world.

Humanity has left behind a lifeless Earth - but there are still items of value. Forgotten seed vaults will provide new plant species adapted for the harsh conditions. Information databases may interest your supervisors in space - and perhaps reveal what exactly happened.

But you may also stumble upon danger. Automated factories from ancient resource wars still mindlessly consume and pollute, guarded by autonomous drones. If you want to save the environment, you will need to stop them.

You land in a scorched and dry region of Earth. The air is polluted and the soil dries soon after it rains. Plant and protect resilient pioneer species to stabilise the soil. Unlock more complex plant species as you progress.

Use technologies like biochar, weather manipulation and air filters to capture CO2 and manage the Earth’s temperature.

With every step, the environment around you changes - can you transform it from a lifeless desert into a lush forest?

This game is in development. It was created as a graduation thesis at the Tomas Bata University in Zlín.
