Cinderbelt is a top-down 3D space game that runs in the browser. You mine asteroids, trade, and assemble your ship from parts on a grid.

You then explore an endless, sectorised universe and fight the Rust pirates, who fly ships built from parts just like yours. The game is available in English, Slovak and German.

• Infinite deterministic universe. Space is generated from a seed in 200x200 chunks; only your changes are saved. Irregular named sectors have a security level (Quiet, Guarded, Contested, Pirate), their own environment, sky and music.
• Economy. Fuel from ice, energy from reactors, cargo mass, tiered crafting, a market, and contracts (delivery, mining, hunt, rescue, survey, escort, fortress and more).
• Guild convoys and Watch patrols. Link up with trade convoys to trade or refuel, take escort contracts, restore Guild relays to make a sector Guarded.
• Part-based combat. Shots hit the part they reach, shields absorb first, severed sections become separate wrecks; tow wrecks with the tractor beam and salvage them.
• Pirate clans and Rust Fortresses. Clans with their own ship models, named captains with bounties, and fo
