Heavenlode

Heavenlode is a free-to-play, online, sandbox SciFi game with persistent open worlds, solar systems, resources, crafting, trade, unique quests, and so much more.
Explore hand-crafted planets to progress the storyline, or visit an infinite number of worlds each with their own unique biomes and resources.
Expeditions
Choose how deep you want to go. Quick, focused expeditions allow you to focus on gathering resources to build your next ship, or prepare accordingly for longer, competitive expeditions, and discover what mysteries the furthest reaches of the cosmos have to offer. 
Crafting
Every solar system is unique, and it's a one-way ticket: one way in, no way out. Every ship is disposable, so you can always build new ships, sell your resources and crafting services to other players, or make your riches by strategically hiring other players to amass your wealth.
Rent Your Solar System
Did you discover a solar system that is particularly valuable? Then you can set laws on those planets and grant access to players--for a fee. Be sure to deploy Security Droids to enforce your laws, or risk having your goods stolen by pirates.
Rebuild Pardizo
You're stuck in the underbelly of the mysterious planet Pardizo: a city slum known as the Backslat. Help improve the lives of the citizens by completing missions and rebuilding amenities, which also improve your expeditions and allow you to farm your own space crops.
