Ostranauts How to Play: Full Starter Walkthrough

Learn Ostranauts how to play with this beginner-friendly tutorial covering K-Leg station, ship salvage, crew management, and early credits for new captains.

Learning Ostranauts how to play can feel overwhelming on your first shift at K-Leg station. This Ostranauts tutorial condenses the early-game grind into a focused walkthrough so you stop losing crew and start turning salvage into profit faster.

Ostranauts is a hardcore noir space-sim RPG from Blue Bottle Games, set in the same universe as NEO Scavenger. You begin as a scavenger working out of K-Leg station, scraping a living off derelict hulls drifting through the inner system. The 1.0 release on August 3, 2026 (version v1.0.0.7) marks the end of an Early Access run that started back in September 2020, and the systems are now deep enough that a structured Ostranauts walkthrough saves you weeks of trial-and-error. Below is the full roadmap from character creation to your first paid-off loan.

Boot Up: Creating Your Captain at K-Leg Station

Every Ostranauts tutorial starts at the same place: a blank resume and a beat-up starter pod docked at K-Leg. The character creation screen does not hand you a backstory because the universe does not care who you were, only what you can do on your first shift. You pick a name, an origin tag, and a small set of starting skills, then boot into the station.

K-Leg is a junkyard port in a decaying orbit, and it is the safest place you will ever sit. The station itself is run by the K-Leg Authority, which sells you your first ship on credit, logs your loan, and offers a small job board. Your very first screen after character creation is the Loan Office, where you accept the starter vessel that defines your next twenty hours of gameplay.

Vanta Cutter25,000 cr55 units2Pirate-prone sectors

The Mule Skiff is the cheapest path through the early game and the recommended pick for your first Ostranauts walkthrough. Solo runs mean you keep every credit you earn, and the small frame is easier to maneuver when you are still learning the Newtonian physics flight model. Picking the Trident Hauler upfront is a common mistake because three crew slots also means three mouths to feed, three salaries to pay, and three chances to watch a crew member die from a missed meal.

The First Three Shifts

Your first three in-game shifts serve as the game's tutorial window, and the structure is consistent across every Ostranauts beginner session:

  • Shift 1 — Station Induction: Meet the loan officer, dock your starter, and grab the free work uniform from the locker.
  • Shift 2 — Tool Calibration: Learn the suit HUD, install a basic salvage tool, and run a tutorial derelict parked in safe space.
  • Shift 3 — First Contract: Accept a low-risk K-Leg job that pays roughly 1,200 cr, enough to buy three days of rations.

According to the official wiki, the K-Leg starter derelict contains a set of tier-1 components that are exactly what you need to upgrade your starter ship. Do not skip the tutorial derelict because it is the highest-value, lowest-risk loot in the entire game.

Core Mechanics Every New Player Must Learn

The Ostranauts tutorial layer introduces real systems quickly, and the three pillars that define every session are flight, salvage, and ship management. Each one has a learning curve, and each one punishes careless play, which is why this section of the Ostranauts walkthrough focuses on the mechanics first.

Newtonian Flight Without a Net

Flight in Ostranauts is not arcade-style. There is no auto-level, no thrust compensation, and no invisible walls. You apply thrust, you drift, and you keep drifting until something stops you. The interface shows a velocity vector, a heading arrow, and a small fuel gauge that drains fast if you burn hard.

ActionInputCommon Mistake
Forward thrustHold WBurning past the salvage and running dry
RotationMouse dragOver-rotating, missing dock approach
BrakeSpacebarTapping too early, ending up still drifting
Cut enginesCForgetting to cut, drifting into a wreck

The single most important flight habit is to cut engines before you reach your target and let momentum carry you the last few hundred meters. New players who chase every correction with thrust burn through their fuel reserve inside a single shift, then sit dead in space waiting for rescue. For a deeper dive on flight planning, the Ostranauts starter guide covers altitude selection and the safe approach pattern for derelict wrecks.

Salvage Loops and Derelict Structure

Every derelict you can board is built from the same modular grid the player uses for ship construction. Individual grid squares are called tiles, and each tile can be cut free with a salvage tool if you have the right consumable. The standard loop is:

  1. Dock with the wreck at a slow approach.
  2. EVA across and attach to the hull.
  3. Cut tiles with the Plasma Cutter until your cargo is full.
  4. Return to your ship, undock, and sell at K-Leg.

The plasma cutter runs on cutting cells, which are consumable and expensive. According to community data, the average new player wastes about 30% of their cutting cells on tiles that cannot be sold for more than the cell cost. The trick is to scan the hull first with the handheld scanner, which tags every tile with a value estimate. Only cut tiles flagged green or above.

Ship Building on the Grid

Ship building is the most creative system in Ostranauts, and it is also the one that ties every other mechanic together. The grid is one meter per tile, and rooms are defined by snapping compatible modules together. The starting Mule Skiff has four rooms, and the early upgrade path is to add a fifth room for storage.

ModuleWeightPower DrawCrew Need
Bridge200 kg50 W1
Engine Room350 kg0 W (generates)1
Storage Bay150 kg5 W0
Bunk Room100 kg20 W0
Galley120 kg30 W0

The galley is the unsung early-game module. A bunk room gives you a place to sleep, but a galley is what lets you actually process the raw rations you salvage into meals that keep your crew alive for full shifts. Without one, the crew rating drops every cycle and you start losing follow-on crew to desertion. For the full module tree, the official Ostranauts wiki breaks down every component and its adjacency rules.

Crew, Health, and the Living Ship

Once you have a ship and a derelict under your belt, the next layer of the Ostranauts tutorial is the crew simulation. Your NPCs are not disposable bots. They have a body that can starve, a mood that can collapse, and a payroll that can bankrupt you.

The Three Core Crew Stats

Every crew member has three tracked metrics that you watch every shift:

  • Health: Drops from injuries, exposure, and combat. Below 30% the crew member blacks out.
  • Nutrition: Drops from time, work, and stress. Below 20% they stop following orders.
  • Morale: Drops from low pay, bad food, and deaths. Below 10% they may mutiny.

Each stat has a soft threshold and a hard threshold. The soft threshold is when you should already be intervening with a meal, a stim-pack, or a bonus. The hard threshold is when the game kicks you out of the action with a crew-down event. For a complete stat reference, the Ostranauts beginner guide covers the simulation tick rate and the exact thresholds.

Feeding the Crew on a Budget

Food is the hidden credit sink that kills most first-time captains. The starter ship comes with twelve units of Basic Rations, enough for one crew member for about three days. The first thing you should buy at K-Leg is a Galley Module if you do not have one, plus a stock of Bulk Protein. Bulk Protein is cheap, weighs almost nothing, and turns one unit into two meals at the galley.

Ration TypeCost per UnitMeals per UnitMorale Boost
Basic Rations15 cr10
Bulk Protein20 cr2+5
Synth Stew45 cr3+15
Premium Filet120 cr4+40

The standard early-game rule from the community is to keep Bulk Protein as your floor and Synth Stew as your upgrade once you can afford it. Premium Filet is a luxury that pays off in high-stress deep-space runs where morale drops fast, but it is a waste of credits in the K-Leg neighborhood.

Earning Credits and Working Off the Loan

The K-Leg loan is the timer that keeps the early game moving. With the Mule Skiff you owe 18,000 cr at 6% interest, and the loan officer will start docking your pay if you miss a payment. The fastest paths to paying off the loan, ordered by risk, are salvage, courier contracts, and station jobs.

Income Sources Compared

SourcePay per ShiftRiskCapital Needed
Derelict Salvage800 - 4,000 crMediumCutting cells
Courier Contracts1,200 - 2,500 crLowNone
Station Jobs600 - 1,000 crNoneNone
Trade Runs2,000 - 6,000 crHigh10,000+ cr

The beginner-friendly blend is two courier contracts and one salvage run per shift. Couriers pay predictably and introduce you to the navigation system without burning cutting cells. The one salvage run covers the cost of the cells and then some, while also feeding your upgrade pipeline. For a full breakdown of the early-game economy, see the Ostranauts getting started guide.

Avoiding the Three Early Bankruptcies

Community reports consistently flag the same three paths that bankrupt new players. The first is hiring crew before you can feed them. The second is buying a bigger ship before you have paid off the starter. The third is taking a high-paying pirate job during your first week in the black.

  • Hiring too fast: A second crew member doubles your food and salary costs without doubling your income until you have a working galley.
  • Upgrading too soon: The Trident Hauler is a 32,000 cr loan on top of your existing 18,000 cr. If you take it on day ten, you are working two jobs to pay for one ship.
  • Pirate work too early: Pirate contracts pay 5,000+ cr but require you to fight, and the cheapest combat-ready ship costs more than your starter loan.

The Ostranauts walkthrough rule is simple: pay off the Mule Skiff, save 10,000 cr in reserve, and only then look at bigger ships. The discipline compounds because every upgrade you make after that point is funded by surplus, not debt.

First Steps Into the Wider System

Once your starter loan is cleared and you have a working ship, the game opens up. You can leave the K-Leg neighborhood, take on faction jobs, hire a real crew, and start building mid-game ships. The first-zone progression path most experienced players follow is K-Leg → Vanta BeltHelion RingOuter Reach. Each ring is further from the sun, more dangerous, and more profitable.

ZoneDistance from K-LegThreat LevelAvg. Pay per Shift
K-Leg Neighborhood0Low1,500 cr
Vanta Belt1 jumpMedium3,500 cr
Helion Ring2 jumpsHigh7,000 cr
Outer Reach3+ jumpsExtreme15,000+ cr

The transition out of K-Leg is also where the Ostranauts complete guide starts to pay off, because the Vanta Belt introduces the first real combat encounters and the first faction reputation system. You do not need to rush there. Most players spend twenty to thirty shifts in the K-Leg neighborhood before they feel ready.

Building Your Long-Term Plan

When you start planning beyond the starter loan, four long-term goals define the mid-game:

  • Ship specialization: Decide whether you want a salvage rig, a trade hauler, or a combat frigate. Each path requires a different module loadout.
  • Faction reputation: The K-Leg Authority, the Salvage Guild, and the Free Captains each offer unique contracts. Pick one as your primary and grind reputation through their job boards.
  • Crew quality: Move from hired help to skilled specialists. A high-tier engineer or pilot will pay back their salary within five shifts.
  • Mod integration: The game ships with text-data mod support, and the Steam Workshop has hundreds of community ships and outfits. The right mod can double your effective income.

According to the official wiki, the developer's long-term roadmap includes expanded faction storylines and a deeper trade simulation, so the systems you are learning now are the foundation for content that ships in future patches. The full release on Steam is verified for Steam Deck, so the same Ostranauts tutorial works whether you are playing on a desktop or handheld.

Your first session should end with a working ship, a paid day on your loan, and at least one crew member who is not starving. Anything beyond that is a bonus. The Ostranauts how to play curve is steep, but the systems are consistent, the community is active, and the payoff is one of the deepest space-sim RPGs on the platform. What kind of captain are you planning to build first — a solo salvage runner, a faction loyalist, or a pirate hunter?

Frequently Asked Questions

How long does the Ostranauts tutorial take to finish?

The in-game K-Leg tutorial window covers the first three shifts and runs about 30 to 45 minutes for a new player. The full onboarding loop, including paying off the starter loan and unlocking the Vanta Belt, takes most players between 10 and 15 hours of playtime.

Can I play Ostranauts solo with no crew?

Yes, the Mule Skiff is designed for solo play and works well through the entire early game. Solo runs are the simplest way to learn salvage, flight, and the K-Leg economy. You can hire crew later once your income comfortably covers salaries and food.

What is the best starter ship in Ostranauts?

The Mule Skiff is the best starter for new players because it has the lowest loan, the lowest operating cost, and the smallest crew requirement. The Trident Hauler pays off faster per shift but triples your overhead, which is brutal during the first ten hours.

Does Ostranauts support mods on the 1.0 release?

Yes, the game supports text-data mods natively and the Steam Workshop has hundreds of community-created ships, outfits, and crew. Mods are loaded from the launcher and most of the popular ones are updated for the 1.0 patch within weeks of release.

Is Ostranauts playable on Steam Deck?

Ostranauts is Steam Deck verified and runs well on the handheld at native resolution. The interface is designed for mouse and keyboard but the layout scales cleanly to the Deck's trackpad and controller input, so you can use the same Ostranauts walkthrough on either platform.
