Become a Living World

You are the Worldeater: an enormous mechanical planet carrying an entire civilization across your surface.

The people living on you need land, water, atmosphere, food, and metal. Your own body needs those same resources to keep moving. To survive, you must travel through the galaxy, consume other worlds, and turn their remains into everything your inhabitants need.

Every planet offers something different.

Worlds close to their stars contain valuable iron and heavy metals, but reaching them means enduring tremendous heat. Gas giants can restore your atmosphere. Frozen outer planets provide rock, ice, and water. Rare habitable worlds contain life, knowledge, and unusual adaptations.

Choose carefully. Every planet you consume destabilizes its star.

Eat, Escape, Repeat

Enter a solar system, determine what your body needs, and consume the right worlds before the star becomes unstable.

Once you leave, the abandoned system is destroyed behind you.

Travel across a persistent galaxy map, choose your next destination, and keep moving. If you somehow consume your way through an entire galaxy, another waits beyond it.

Carry a Civilization

The inhabitants living on Worldeater are not merely passengers.

They build cities, maintain your organs, produce Knowledge, and construct massive Surface Projects. As their population grows, they make you stronger, but they also consume more resources.

Keep them alive by balancing:

• Iron
• Rock
• Gas
• Water
• Life
• Population
• Morale
• Body integrity

Shortages visibly damage both Worldeater and the civilization living on it.

Build a Mechanical Planet

Spend Knowledge on Surface Projects that permanently change your abilities and appearance.

Develop:

• A larger mechanical maw
• Reinforced tectonic armor
• Atmospheric organs and vents
• Internal oceans and cooling canals
• Migrating gardens
• A second mechanical heart
• Digestive storage vaults
• Expanding symbiotic cities

As Worldeater develops, its body grows larger and gains city districts, lights, armor seams, industrial structures, energy conduits, grinders, and enormous external machinery.

Control a Planet-Eating Machine

Use the Tractor Beam to drag distant planets into your grinders, but watch your Iron and Gas reserves.

Expel your own atmosphere as Thrust to accelerate through space and escape unstable stars.

Planet consumption takes time. Once the Tractor has delivered a world to your grinders, the process cannot be stopped.

Current Development Status

Worldeater is actively being developed.

The current version contains the central survival loop, galaxy travel, planet consumption, civilization management, Surface Projects, visual progression, mobile controls, and save support.

Future updates are planned to include additional solar-system types, functional black holes, more planetary hazards, expanded civilizations, further upgrades, a full tutorial, and a more advanced custom Worldeater form.
