• Explorers can now decide to play with different rule sets, across three game modes:
• Normal mode is the original chilled exploration experience
• Creative mode allows players to explore the universe without limits, and build a huge base
• Survival mode really changes the game, creating a much more challenging endurance experience

• Claim your home planet by finding an uninhabited base and creating your own, fully bespoke outpost.
• Construct your homestead for shelter, using modular structures and decorations, replicated from resources gathered while exploring
• Recruit alien lifeforms to help research new technology. Farming, engineer, weapons and science specialists are hirable from Space Stations
• Use Terminus Teleporters in Space Stations to teleport to and from your base at will
• Expand your base with storage containers to stockpile precious resources and rare products
• Find an even more beautiful location and you can simply dismantle your previous homestead to refund all of the spent resources
