Seafarer: The Ship Sim 1.0 Leaves Early Access, Recommends 64GB RAM

Seafarer: The Ship Sim 1.0 Arrives on Xbox Series X|S and Leaves Steam Early Access​

The full release was announced well ahead of time. In early September, astragon announced that Seafarer: The Ship Sim will leave Early Access on Steam on September 24, 2026, marking the game's full PC release and its first appearance on the PlayStation 5 and Xbox Series X|S, according to Simulation Daily. The developer's own Steam announcement from September 3 used the same date and said the day marked both the end of Early Access and the game's first console launch. Launch-day coverage from TheXboxHub confirms the game has finally reached its full 1.0 launch, bringing its life at sea to Xbox Series X|S, PlayStation 5 and PC.

The publisher's launch press release carries a dateline that puts the release at the wrong time. It begins "Duesseldorf, Germany, September 26, 2026 – Seafarer: The Ship Sim is now available", even though the release itself was published on September 24. The Xbox Store listing gives a release date of 9/24/2026. The full-release patch went live on Steam as build 25438930 on September 24. The correct launch date is September 24, and the September 26 dateline appears to be a typo.

The game had a long public development. Since launching in Steam Early Access on October 7, 2025, Seafarer: The Ship Sim has received major updates that expanded its ships, missions, gameplay systems, and progression. The developer lists five major Early Access updates:

• The LNG & Bulk Update added the Big Trip container ship plus the Bulk Willy and Nordic Duchess for bulk cargo and liquefied natural gas (LNG) jobs.
• The Rescue Update brought two new police ships, Salvation and Grace, added rescue operations and overhauled inspections.
• The Immersion Update reworked the first three campaign chapters and added the radio and daily challenges.
• The Career Update introduced Free Trade, Reputation, work shifts, drone operations and new campaign chapters.
• The Co-op Crew Update, released August 18, 2026, added multiplayer for up to four players on selected cargo, firefighting and rescue operations.

The game is a non-combat "working" simulator, the genre astragon is known for. The developer describes it as a game where you take the helm of various vessels solo or in multiplayer with a crew of up to 4 players, explore a vast open world inspired by Northern Europe, and take on maritime jobs ranging from cargo transport and rescue missions to firefighting, patrols, and unexpected events. There is also a story campaign about a captain named Teddy, involving sabotage and piracy. It uses Unreal Engine 5 and NVIDIA WaveWorks 2.0 to render the ocean.

The Steam and Epic Price in the Launch Release Looks Out of Date​

The launch release lists the game as now available for PC for $24.99 / ₤20.99 / 24.99€ (SRP) via Steam and Epic Games Store as well as for PlayStation®5, and Xbox Series X|S for $34.99 / ₤29.99 / 34.99€. The console price matches other records. The PC price conflicts with astragon's own earlier statements.

The September pre-launch release, as reported by Chris Jones Gaming, said the game was now available for PC in Early Access for $24.99 / ₤20.99 / 24.99€ (SRP) via Steam and Epic Games Store, and that with the Full Release on September 24, the price will be raised to $29.99 / ₤24.99 / 29.99€. The developer's September 3 Steam post agreed, saying the game would stay at its Early Access price until launch and then rise to €29.99. The $24.99 figure in the launch release is the old Early Access price. It was most likely carried over from earlier boilerplate by mistake.

Unless astragon reverses the planned increase, expect to pay $29.99, £24.99 or €29.99 for the PC version at 1.0. As always, the actual price at checkout depends on your region and any running discounts.

On Xbox, the US Microsoft Store lists the base game at $34.99. It also sells a Voyager Edition from $44.99, which adds the $10.99 Voyager Pack. That pack includes the Gull, a ship that has a drone from the start instead of needing it unlocked, plus the Green Star tugboat and six captain clothing items. Anyone who pre-ordered on console already has it: players who pre-order either console version will receive the Voyager Pack at no additional cost, which includes two additional ships and a selection of cosmetic items.

The Windows 11 Recommended Spec Asks for 64 GB of RAM​

Seafarer's minimum PC spec is fairly ordinary for a 2026 Unreal Engine 5 game. The official site lists 64-bit Windows 10, DirectX 12, 16 GB of RAM and 42 GB of free storage. The minimum CPU is an Intel Core i3-12100F or AMD Ryzen 5 3600, and the minimum GPU is an NVIDIA GeForce RTX 2060 (6 GB) or AMD Radeon RX 5600 XT (6 GB). The developer states that a dedicated graphics card is required, so integrated graphics are not supported.

The recommended spec is far higher:

Two entries are unusual. A 64 GB RAM recommendation is rare for a game in this price range, and it quadruples the minimum. The developer doesn't say which resolution, settings or frame rate either tier targets, so there's no official way to know what 16 GB or 32 GB will deliver in practice. The AMD GPU is listed as a "Radeon RX 7950" with 16 GB, which doesn't match any product name we can confirm. Treat that entry with caution rather than shopping for it by name.

Moving from Windows 10 to Windows 11 between the two tiers is less important. Windows 10 is supported at minimum, so the game does not require Windows 11. The developer simply lists Windows 11 in its recommended spec.

The 1.0 patch includes one PC-specific graphics fix worth knowing about. It fixes a GPU crash that could happen when you changed window mode with DLSS Frame Generation turned on. It also fixes invalid calculations in the GPU wind simulation and frame-rate drops during a Patrol Job. These fixes come from the developer's patch notes. No outside testing has confirmed them yet.

Crossplay and Four-Player Co-op Work on Xbox, but Need a Subscription​

Co-op was the last major Early Access feature, and at 1.0 it extends to consoles. The Xbox Store lists online co-op and online multiplayer for 2–4 players, single-player, and Xbox cross-platform multiplayer and co-op. The publisher says the game has full crossplay across all supported platforms, which would include Steam, Epic, PS5 and Xbox. The Xbox listing confirms cross-platform play, but not every platform pairing, so the complete crossplay coverage comes from astragon's claim.

Xbox players need to know about one cost. The Xbox listing says the game requires an online multiplayer subscription on console, Game Pass Core or Ultimate, sold separately. Solo play and the campaign don't need one, but joining a friend's crew from an Xbox Series X|S does. The Xbox page also lists PC next to Xbox Series X|S under "Play with". Neither the publisher nor the official website names a Microsoft Store PC version or Xbox Play Anywhere support, and the official site lists only Steam and Epic as PC stores.

Different jobs suit different crew sizes. According to the notes for the Co-op Crew Update, cargo work suits two players: on the Big Trip, for example, two players can run both cranes at the same time. Firefighting and rescue missions make room for four, with one player steering and up to three handling extinguishers or lifebuoys.

The 1.0 patch includes a long list of multiplayer fixes, which is useful context for anyone who tried co-op in August:

• Players getting stuck in the Tug & Tow crouching animation or the rescue net has been fixed.
• Crashes when switching to an inspection vessel while another player was using a drone have been fixed.
• Free Trade rewards now go to clients correctly, and invisible containers no longer appear on other players' vessels.
• Docking and late-join synchronisation, weather sync, crane movement and vessel physics replication for clients have all been improved.

What the 1.0 Patch Changes for Steam Early Access Players​

If you already own the game on Steam, 1.0 arrives as a normal update. The eight new missions split into four main missions and four side missions:

• Flying Dutchman unlocks in Crescentport once you reach the highest harbour reputation there.
• A Light on the Horizon is available in Stettach.
• Forbidden Freight unlocks in Stettach at the highest harbour reputation.
• Eddy's Delivery Service is available in Mettington, Crescentport, Stettach and Drachdelen.
• Four side missions (Seal Appeal, Discord, A Sound Anomaly and Secrets of the Deep) appear while you're travelling at sea rather than at a harbour.

Progression is faster. Fast Travel now unlocks at Level 1 and Crew at Level 2, and special and campaign missions pay more. All campaign missions and three special missions can be replayed in Quickplay, but only after you've completed them in single-player. Free Trade got another balance pass: auto-completing a Free Trade operation now sets the price by the cargo left, not a fixed amount. Exploits involving cancelled trades have also been closed.

For controllers, steering and throttle now have separate dead zone settings. On PC, Push-to-Talk can now be rebound. The patch also restores previously unlocked Steam achievements and fixes several progression blockers, including a freeze in Campaign Mission 2, a dialogue crash in Campaign Mission 5 caused by an invalid save state, and an LNG arm that wouldn't reconnect after a mission restart.

The developer has also said what is not in this build. The first post-launch update will improve pacing in Campaign Mission 1, polish Campaign Mission 6, add more tutorial cards, and add an Auto-Travel option that takes you straight to the harbour for your next campaign mission. The developer describes that update as planned. It has no firm date beyond a "Week 1" label.

What this means for you​

If you already played the Steam Early Access version, the free 1.0 update is worth installing now. If you're new on PC, check the real store price and your RAM before you buy. If you're on Xbox, budget for a subscription if you want to play co-op. The biggest open question for Windows players is how the game runs below the 64 GB recommended spec, and that will only be answered by testing on real hardware, not by the spec sheet.

• The launch date is September 24, 2026. The September 26 dateline in astragon's launch release is an error.
• Expect the Steam and Epic PC price to be $29.99 / £24.99 / €29.99 at full release. The $24.99 figure in the launch release matches the old Early Access price.
• The minimum spec is 64-bit Windows 10, 16 GB of RAM, a dedicated 6 GB GPU such as an RTX 2060, and 42 GB of storage. The recommended spec asks for Windows 11, 64 GB of RAM and an RTX 4070-class card.
• On Xbox Series X|S the game costs $34.99, supports 2–4 player online co-op with cross-platform play, and needs Game Pass Core or Ultimate for online play on console.
• If you play with DLSS Frame Generation on, the 1.0 patch fixes a GPU crash that could happen when you changed window mode.
• Auto-Travel and the Campaign Mission 1 pacing changes are coming in the first post-launch update, not the 1.0 build.

With its 1.0 release, Seafarer: The Ship Sim moves from a single Steam Early Access build to three platforms with crossplay. The launch patch fixes many of the co-op and progression bugs from the August multiplayer update. For Windows buyers, the pricing is the only real point of confusion, and astragon's own earlier statements show the $24.99 figure is out of date. The next milestone is the "Week 1" update with Auto-Travel and campaign fixes. Players who struggled with the opening mission may want to wait for it before starting the story.
