Ostranauts achievements guide: all 31 Steam 1.0 unlocks sorted by salvage, ship, crew, Ceres Affair story, and bounty routes — plus global rates and tips.
Ostranauts 1.0 (Steam app 1022980) added 31 Steam achievements on the August 3, 2026 launch — the first time the long-running early-access build tracked profile unlocks. Unlike a short narrative game, this Ostranauts achievements list spans hundreds of hours: tutorial salvage, fusion reactors, Ceres Affair investigation threads, deep-system hops, and bounty combat. Verified August 16, 2026 · Steam.
Global unlock rates at launch tell a familiar story for hardcore sims: Traveller and Into The Black sit above 5%, while 79AU, Weaver's Needle, and most endgame station hops still read 0.0% — not because the feats are broken, but because most buyers are still paying OKLG debt. This page groups every official unlock by activity so you can chase them alongside normal play instead of treating 100% as a separate game.
Open-ended sandbox — hundreds of hours for mastery

Which achievements unlock during early salvage?
The first dozen hours at OKLG naturally feed the salvage and start buckets. None of these need Ceres, Venus, or a finished fusion loop — they reward doing what the beginner guide already teaches.

Traveller and Into The Black — creation and first undock
Traveller fires when you finish Build-a-Resume and spawn aboard your loan ship — every profile gets it. Into The Black needs one successful undock from K-Leg; if you panic on RCS, practice in the tutorial lane before committing. Pair with the beginner guide EVA prep section so your first departure is not also your first vented hab.
Tutorial Derelict and Return to K-Leg — the tutorial strip
Tutorial Derelict tracks the guided wreck through your first derelict boarding — follow the on-screen prompts through airlock, strip, and return. Return to K-Leg confirms you docked safely with salvage in cargo — dying on EVA or abandoning loot does not count. These two are the achievement mirror of the salvage guide first-run checklist.
Entrepreneur and Legal Salvager — kiosk literacy
Entrepreneur is the simplest economy unlock: sell anything at any kiosk. Scrap counts — feed it a cracked tile on day one. Legal Salvager needs the official Salvage License from OKLG (~5k / 24h per the money guide). Buy the permit on a day your airlock already holds Licensed-tier modules so both achievements and profit land together.
Which achievements need ship building or crew?
Ship achievements assume you moved past loan-ship survival: a working reactor, nav console upgrades, and time in the Ship Editor. Crew achievements need social systems — recruitment and station medical care.

Reactor — fusion grid online
Reactor demands a working fusion reactor aboard your hull — not merely owning parts. Route Sulaiman ICFR feed ports, purge sequence, and breaker output until the grid stays stable under load. The reactor guide walkthrough matches this unlock; brownouts during startup do not count as "working."
Custom Console and Ship Editor — layout milestones
Custom Console unlocks when you install a new module into your nav console — treat it as a ship-building puzzle, not a store purchase. Ship Editor only asks you to open the editor; patch one floor tile or move a crate if you want the achievement without a full refit. See ship building for grid layers and conduit rules.
Firm Handshake and Health-Fare — crew and clinic
Firm Handshake rewards convincing a spacer to join your crew through the recruitment social-combat flow — salary, Death Pay, and trait compatibility matter. Health-Fare is simpler: use the Medical Kiosk on K-Leg once. Burned spacers and failed EVA runs make the clinic visit natural; see crew guide before you hire three specialists you cannot feed.
Super Fast Forward — time skip
Super Fast Forward triggers when you skip an hour or more of time from the time controls while safely docked or in a stable hab. Use it during long reactor charge waits — not while suffocating on EVA.
Which achievements come from gigs, trade, and the black market?
The economy column rewards systems the money guide covers: Gig Nexus contracts, Fixer access, bulk cargo profit, asteroid mining, and faction scrip. Most sit in mid-game when OKLG debt is boring but deep-space fuel still costs real dollars.

Gignexus and Black Marketeer — OKLG side hustles
Gignexus completes when you finish any Gig Nexus job — OKLG courier gigs inside the station count before you own a flying hull. Black Marketeer needs the Fixer in Mescaform bar to trade with you, either by winning the opening social combat or reaching Friend status (or starting with Fixer as a Build-a-Resume contact). Both pair naturally with Entrepreneur kiosk sales on the same dock day.
Cargo Trader, Asteroid Miner, and Sixteen Tons — mid-game capital
Cargo Trader checks profitable long-haul bulk trading between Cargo Kiosks — you need pod mounts, stock capital, and a route that beats salvage hourly rate. Asteroid Miner needs a successful asteroid deposit extraction — tooling, RCS, and often a stable reactor. Sixteen Tons tracks earning scrip from a faction; faction jobs and standing gates live deeper in the sim than day-one scrap runs.
How do I complete the Ceres Affair story achievements?
Four achievements — PPP, Ms M, VHS, and 79AU — form the Ceres Affair investigation cluster. Steam describes them as uncovering secrets, a missing lounge singer, V.H.S. tape origins, and finally the whole truth. All four still showed 0.0% global at 1.0 launch — expect multi-station clue chains, not a single dialog button.

PPP
Uncover the secrets of the Perpetual Protein Project
Perpetual Protein Project — follow station rumors and job board leads
Ms M
Uncover the location of the missing lounge singer
Missing lounge singer — bar NPC threads on OKLG and outbound stations
Capstone — requires prior clue threads; plan before selling quest items
Treat clues as cargo
Investigation items often behave like physical loot — stashing them in the wrong crate or selling them at the Scrap kiosk can soft-lock branches until you find a duplicate. Keep a quest crate aboard pressurized hab space and label it in your head the same way you label premium salvage.
PPP and Ms M — mid-story anchors
PPP (Perpetual Protein Project) and Ms M (missing lounge singer) are the usual mid-layer gates. Talk to every named NPC in Mescaform after gig runs; cross-reference Fixer chatter with Gig Nexus flavor text. Players report lounge-singer leads mixing station bar scenes with off-station destinations — bring a legal transponder before chasing flags.
VHS and 79AU — end-layer truth
VHS asks who produced the V.H.S. tapes — expect mixed media loot, derelict logs, and dialog trees. 79AU is the whole truth capstone; do not rush it on a ship that cannot reach Ceres, L.A., or other late-map nodes. LA Unlocked (transit to the bottom of L.A.) overlaps exploration achievements — route them on the same save when you commit to the Affair.
Which achievements need deep travel or combat?
Exploration achievements punish short-loop debt grinders: Untime, Flotilla, Weaver's Needle, Venus, Ceres, Slow Boat ferry rides, and LA Unlocked. Bounty achievements need weapons online — Fire At Will! and Bounty Hunter — plus Racer for Aero Race victory.

Deep stations and the Untime
Untime marks your first full Untime — a major time / travel milestone in the 2079 map. Flotilla and Weaver's Needle need deliberate deep-space routing, spare RCS, and often a fusion-powered hull. Register your transponder via the transponder guide before hostile scan zones turn detours into combat.
Venus, Ceres, and L.A. — endgame map nodes
Venus and Ceres unlock on first successful dock at any station in those regions — fuel planning and life support margins matter more than raw distance. LA Unlocked requires reaching the bottom of L.A. and unlocking transit — overlap with Ceres Affair threads; do not treat it as a sightseeing hop.
Slow Boat and Racer — alternate travel
Slow Boat rewards using the Ferry instead of your own ship — useful when your hull is illegal or vented. Racer needs an Aero Race win — a combat / piloting skill check separate from salvage. Budget repair kits and med supplies.
Fire At Will! and Bounty Hunter — 1.0 combat
Fire At Will! triggers the first time you manually fire a ship weapon — install a turret or railgun, load ammo, and trigger from the combat UI. Bounty Hunter needs a completed bounty cashed in at a posting terminal; the money guide bounty section covers prep. Alive captures often pay more but need restraint gear and cargo space.
Full 31 Ostranauts Steam achievement table
Every row below quotes the official Steam description from the 1.0 listing. Global rate snapshots come from public Steam stats at launch — they shift as more players finish long arcs. Sort mentally by rate when planning: anything above ~2% is early-run territory; 0.0% rows are endgame or story-gated.

What is a sensible 100% achievement route?
There is no ironman 100% speedrun — Ostranauts is a sandbox debt sim — but this phased route minimizes backtracking on a single long save plus one fresh profile if you want Traveller again.
Do07Parallel Ceres Affair — PPP → Ms M → VHS → 79AU without selling clue items
Do08Optional — Aero Race win on a save with spare cash for entry fees and repairs
One save vs alt profiles
Everything except Traveller can live on one captain if you avoid permadeath. Hardcore players sometimes spin a story save once fusion power and legal registration are solved, keeping investigation crates separate from experimental PvP hulls.
When to stop chasing 0.0% rows
If end-of-shift mortgage still hurts, ignore Weaver's Needle and 79AU until salvage income is routine. Achievement hunting should not vent your hab — dead captains unlock nothing.
Mistakes that stall your achievement sweep
Most stalled achievement profiles are not missing hidden triggers — they are missing ship capability or clue custody.

Quest-dedicated crate; never auto-sort story items
At launch, Weaver's Needle, 79AU, PPP, Ms M, VHS, and most deep-station hops showed 0.0% global — story and exploration gates.
Do achievements sync on Steam Deck?
Yes — same Steam account and cloud rules as PC; unlocks appear on the Steam community profile.
Which achievements unlock in the first week?
Traveller, Into The Black, Tutorial Derelict, Return to K-Leg, Entrepreneur, Ship Editor, Super Fast Forward, and often Legal Salvager / Gignexus if you follow the beginner guide.
Are Ceres Affair achievements missable?
Treat PPP, Ms M, VHS, and 79AU as missable if you sell clue items or skip dialog branches — keep backups before major story beats.
Does bounty hunting tie to achievements?
Bounty Hunter and Fire At Will! — see money guide for 1.0 bounty prep.
