Ostranauts Updates

A dated Ostranauts update hub that separates the 1.0 release, v1.0.0.9 fixes, branch notes, and future verification from speculation.

01

First-run fundamentals

Build an Ostranauts route that protects the next decision

Use a small, observable loop: read the ship and crew, choose one job or salvage target, change one thing, and keep enough fuel, air, food, and return space to learn from the result.

  1. 1
    Confirm the current scope

    Record the Steam base game, version, branch, save, crew state, fuel, air, food, and damage before making a large change.

  2. 2
    Choose one useful task

    Pick a job, movement test, docking approach, or salvage target that teaches one decision without risking the whole campaign.

  3. 3
    Change one function at a time

    Separate ship parts, life support, crew work, cargo, and mods so a result can be traced and reversed.

  4. 4
    Recheck live screens

    Thresholds, AI timing, Workshop compatibility, controls, prices, and outcomes may change; trust the current build and keep dated notes.

New player

Learn the first route

Read the starting-state, first-job, movement, docking, and recovery checks before committing resources.

 Ships

Make the vessel diagnosable

Use ship and construction guidance to balance function, capacity, cost, flight, docking, and repair access.

 Systems

Protect life support

Trace air, food, water, crew needs, skills, debt, saves, and mods as connected system inputs.

 Salvage

Plan the return first

Choose derelicts by risk, manage approach and access, sort cargo, and leave before the run compounds.

Evidence-aware planning

Three choices that keep a run focused

A good next action is observable, reversible, and tied to the current ship, crew, save, branch, and version.

01

Scope first

Confirm base-game AppID 1022980, version, branch, platform, and product boundary before trusting a detailed claim.

Record the scope before acting.
02

One change

Separate movement, ship construction, life support, crew work, salvage, and mod tests so the outcome has a cause.

Make the result explainable.
03

Return margin

Fuel, air, food, crew condition, repair access, cargo weight, and the route home belong in the same plan.

Protect the way back.

Player FAQ

Ostranauts questions

Direct answers for players deciding what to inspect, build, salvage, or verify next.

What is Ostranauts?

Ostranauts is a Steam space simulation about salvaging derelicts, maintaining a ship and crew, managing resources and debt, and making risky decisions in a boneyard.

How should a new player begin?

Start with the beginner guide, record the current version and starting state, then choose one small task that teaches movement, docking, work, or salvage without spending the whole margin.

How do I build a better ship?

Define one problem, keep repair and inspection routes visible, change one function at a time, balance capacity against fuel and repair cost, and test a short flight after interior work.

How should I approach a derelict?

Plan the return first, then control relative speed and orientation, confirm access and life support, recover only useful cargo, and leave before fuel, air, crew, or damage removes the margin.

Are thresholds and AI timings fixed?

Do not assume so. The official page supports the broad systems, while exact thresholds, consumption, pathing, and crew AI timing need current in-game verification.

How do I test a Workshop item?

Keep a clean save and original files, record the item version and branch, test one change, compare the advertised result, and report the exact compatibility conditions.

Is this an official wiki?

No. This is an independent fan guide. The Steam product page and Blue Bottle Games or Kitfox Games announcements remain the authority for official identity and release scope.

Where is the official game page?

Use the Open the Steam page buttons or the official product link in the site footer to open the verified Ostranauts base-game listing.
