Om demon

This demo lets you experience the early stages of terraforming Mars. Progress carries over to the game on Mar 9th*.

Clear the fog by increasing the pressure and form ice. Melt it into water by raising the temperature. Convert martian dust into soil, then green the planet with algae. Plant flowers and trees to generate oxygen and turn the sky blue. Grow forests and create biomes then create life by incubating insects, birds and animals.

Explore an unknown planet. Travel across Mars on foot, by rover, and through the air, reaching distant regions to find resources or to simply watch the results of your terraforming efforts. Discover abandoned stations, ancient machines, and wrecked ships. Visit orbital platforms, and piece together what happened to Earth and those who came before you.

You play as Blossom, a small but capable robot built to survive where humans cannot. Managing energy is central to gameplay: power your movement, tools, and machines to stay operational in a harsh environment. Playing as a robot changes how you interact with the world. Electricity replaces food, so careful energy management becomes key to progress.

Gather Mars’ resources, refine materials, automate using drones, build tools, machines and structures. Unlock blueprints, upgrade your technology, and construct bases that grow alongside the planet, supporting terraforming, exploration, and survival in increasingly complex ways.

Build and customize modular rovers, attach functional modules like batteries, storage, and mining lasers, and chain them into convoys. Drive across the planet, mine on the go, and create fully mobile or stationary outposts wherever exploration takes you. Your base is not tied to one place. It moves with you, enabling true planetary-scale exploration.
