Sea of Thieves Achievements Overview
Sea of Thieves has 293 achievements on Steam, and the Xbox list is separate and larger, though achievements earned on Xbox unlock on Steam automatically at your first sign-in there. The rarest sit at 0.1 percent global unlock, and the newest of those, like the Custom Seas pair So. Much. Silver! and Tentacled Tribute, are rare because they are recent, not because they are hard. Most achievements are tied to the commendation system, not one-off unlocks, so the real completion work is grinding commendations.
Sea of Thieves has one of the longest achievement lists on Steam, and almost none of it is the kind you unlock by accident. Most are tied to commendations, so they want you to do something 100 times, not once.
The numbers
| Steam | Xbox | |
|---|---|---|
| Achievement count | 293 | Larger, separate list |
| Cross-platform sync | Xbox unlocks arrive at first sign-in | One-way, Xbox to Steam |
The two storefronts maintain different lists, and Steam prunes legacy unobtainable entries the Xbox list keeps, so the counts never match. Underneath, commendation progress is account-wide, and achievements earned on Xbox unlock on Steam automatically after your first sign-in there, per Rare's own support FAQ. The documented direction is Xbox to Steam only, and the sync has missed batches for some players, so a completionist should still decide which platform is home before starting. More on the platform split in Crossplay and Platforms.
The rarest achievements on Steam
Ten achievements sit at or below 0.2 percent global unlock.
| Achievement | Global unlock | Added with |
|---|---|---|
| Tentacled Tribute | 0.1% | Season 20, Custom Seas |
| So. Much. Silver! | 0.1% | Season 20, Custom Seas |
| Oh Wow, Kegs... | 0.1% | Season 19 |
| Don't Make Me Turn This Ship Around! | 0.1% | Season 19 |
| Mobile Cannoneer | 0.1% | Season 16 |
| Are You Even Trying?! | 0.2% | Season 19 |
| Crew of Bone and Blade | 0.2% | Season 16 |
| Loyalist of the Flame | 0.2% | Season 13 |
| Defender of the Pirate's Life | 0.2% | Season 13 |
| Playing the Part | 0.2% | Season 13 |
A 0.1 percent unlock rate in a game this popular means roughly one player in a thousand, but read the Added column before reading difficulty into it. So. Much. Silver! and Tentacled Tribute arrived with Custom Seas in June 2026 and both unlock inside a session, where the host sets the silver scoring values and spawns creatures up to a Kraken on demand, so they are rare because they are new, not because they are hard. The Season 19 trio is also young. The genuine endurance tests are the older commendation chains, with Mobile Cannoneer wanting every Cannon of Rage commendation before it unlocks.
The most common achievements
| Achievement | Global unlock |
|---|---|
| Legends - 'Cronch' | 93.9% |
| Now Bring Me That Horizon | 92.0% |
| I Wanna Be A Pirate! | 84.5% |
| Handbrake Turn | 83.6% |
| What Shall We Do with a Drunken Sailor? | 76.4% |
The gap between 93.9 percent and 0.1 percent is the whole story of this achievement list. A large majority of players unlock a handful of tutorial-adjacent achievements and stop. Everything else is a long tail.
How the list is structured
Achievements group along the same lines as the game's systems, so this site splits them across three further pages:
| Page | Covers |
|---|---|
| Voyages and Factions | Trading Company reputation, emissaries, voyages, Pirate Legend, selling milestones |
| Combat and PvP | Ship sinking, boarding, cannons, weapons, Hourglass and Allegiance |
| World Events and Tall Tales | Forts, Fleets, Kraken, Megalodons, and every story campaign |
Commendations are the actual work
Most achievements are attached to commendations, tracked in your in-game Reputation menu. A commendation typically asks for a repeated action at increasing thresholds, so the achievement fires at the top tier, not the first.
This changes how you should approach completion:
- Check the commendation menu, not the Steam list. The in-game tracker shows exact progress and remaining counts. Steam shows a locked padlock and nothing else.
- Stack objectives. Almost every commendation ticks from things you would do anyway, so pick voyages that feed several at once.
- Expect long counts. Thresholds in the hundreds are normal.
Before starting a session, open the Reputation menu and look at what is closest to completion. Two or three commendations sitting at 90 percent will finish in one voyage, which is a far better use of an evening than starting something at zero.
Are any achievements unobtainable?
Yes, and this is where the vaulted content matters. The Arena and the Sea Dogs company were removed in patch 2.5.0, taking their content with them. Anything tied to a permanently removed system cannot be earned by a player starting today.
Limited-time event achievements follow the same pattern. If a commendation was tied to a seasonal event that has ended, it is closed.
Do not plan a 100 percent completion run without first checking which achievements are still obtainable. Achievement tracking sites are more reliable than the in-game menu for spotting closed content, since the game does not always flag removed commendations clearly.
Frequently Asked Questions
How many achievements does Sea of Thieves have on Steam?
293 achievements on Steam under App ID 1172620. The Xbox version maintains a separate and larger list, and while Xbox unlocks sync to Steam automatically at first sign-in, the lists never fully match, so completion on one does not grant completion on the other.
What is the rarest Sea of Thieves achievement?
Five sit at 0.1 percent global unlock: Tentacled Tribute, So. Much. Silver!, Oh Wow Kegs..., Don't Make Me Turn This Ship Around!, and Mobile Cannoneer. The Custom Seas pair is rare because it is new, unlocking inside sessions the host fully controls, while the older commendation chains like Mobile Cannoneer are the genuine endurance tests.
Do Steam and Xbox achievements transfer in Sea of Thieves?
Partially. The lists are different, but commendation progress is account-wide, so achievements earned on Xbox unlock on Steam automatically at or shortly after your first sign-in there. The documented direction is Xbox to Steam only and the sync sometimes misses, so completionists should still pick a home storefront.
Are any Sea of Thieves achievements unobtainable?
Yes. The Arena and its Sea Dogs Trading Company were removed in patch 2.5.0, closing anything tied to them, and achievements attached to ended limited-time events are also closed. Check an achievement tracking site before planning a completion run.
What is the best way to track achievement progress?
The in-game Reputation menu, not the Steam list. Most achievements fire from commendations at high thresholds, and the Reputation menu shows exact counts and remaining progress while Steam only shows locked or unlocked.
