Ostranauts Builds Hub

A “build” in Ostranauts is not a talent tree — it is the intersection of character creation choices, starter hull, debt schedule, and the ship systems you grow into while paying shift bills. Blue Bottle Games released 1.0 on 2026-08-03 as a single-player noir space-sim: no multiplayer mode, English-only UI, and a campaign loop that starts at OKLG with salvage permits, Newtonian flight, and mortgages ticking every six-hour shift.

This hub routes you to the four build pillars we document first: career paths, mortgage math, and fusion torch endgame.

Career and starter ship builds

Character creation is a lightweight career simulator. You spend years on Seek Adventure encounters, Work on Self skill purchases, or Seek Ship mortgage shopping until you submit your resume and launch.

High-impact paths include:

• Shipbreaker — salvage skills and hacking lean into boneyard income
• Prisoner and other adventure backgrounds — trait and contact tradeoffs
• Coffin micro-ships — cheap, often life-support-poor, skill-intensive
• Poker debt-free — volatile stolen hull via gambling encounter success

The Starter Careers page compares these routes, skill priorities, and which builds assume you will automate hauls early via PDA Orders.

If you have not left the launch screen, pair builds with Character Creation and Getting Started for OKLG context.

Mortgage as the real difficulty slider

Every financed starter ship carries a mortgage with payments due at shift end — four six-hour shifts per day plus brief Untime. Miss a payment and penalties roll into the next shift. Dock fees, crew wages, and permit costs stack in the same ledger.

Mortgage size is the hidden difficulty setting:

• Higher payments demand faster salvage turnover
• Larger hulls haul more but burn more remass and dock hours
• Ships without life support are cheap until hypoxia invoices arrive

Ship Mortgage breaks starter packages, prepay timing, late-fee traps, and links the mortgage shift planner for table-driven planning. Economic backdrop lives in salvage economy.

Propulsion builds: RCS starters to fusion torch

Early game builds live on RCS and short OKLG boneyard hops — see How to Fly and Dock and Nav Console. Midgame captains flip derelicts, install towing braces, and chase ship rating at the broker kiosk. Endgame builds mount Inertial Confinement Fusion torch drives for interplanetary burns, He3/D2O logistics, and wake-zone law compliance.

Fusion Torch Drive covers reactor components, startup checklists, autopilot plotting, towing brace installation, and ship flipping workflows — including a video walkthrough for brace fitment on cramped airlocks.

Control and tool dependencies by build

Build phase	Lean on
Coffin / solo breaker	Keybinds, manual QAB repair
Mortgaged tug	PDA Orders, Ship Mortgage
Crew salvage	Roster, Hire Crew, zones
Torch courier	Fusion Torch Drive, Map hub

Printable lists live on the Tools hub — atmosphere and salvage checklists assume you already picked a build direction.

Suggested progression

1. Pick a career path in Starter Careers
2. Model shift bills in Ship Mortgage before you Seek Ship
3. Learn flight in How to Fly and Dock
4. Scale income via How to Salvage
5. Upgrade hull through Ship Building
6. Commit to torch logistics in Fusion Torch Drive

After 1.0 and future patches

Fire in the Hold-era additions — Ceres combat, mining, expanded stations — mean older “optimal” hull advice may drift. Check Updates when returning from a break, and Review for release-impression context.

Builds here assume no multiplayer mode and Steam AppID 1022980 mechanics as of the August 2026 launch.
