START HERE // RETURNING CAPTAIN
Ostranauts 1.0 Returning Player Guide
Decide whether to start fresh, keep a 0.15 save, or import an old ship when returning to Ostranauts 1.0.
Quick answer
What you need to know
Start a fresh 1.0 game if you want the safest path to all new station maps and plots. A developer says 0.15 saves technically work, but worlds generated earlier can miss content. 1.0 also adds a Ship Editor option to import ships from old saves.
Choose your return path
Best coverage
Start fresh in 1.0
Choose this for the new station maps, launch plots, Ceres endings, bounty system, and the lowest compatibility risk.
Keep continuity
Continue a 0.15 save
It may load, but the developer warns that already-generated worlds can miss new station and plot content.
Middle path
Import your ship
Use the new Ship Editor import feature to carry an old ship design into a new game while regenerating the world.

- Decide world content vs. continuity.If launch plots matter, prefer a fresh world or ship import.
