Sea of Thieves is about to shrink. On October 1, 2026, Rare announced a new packaging pass for the pirate game. On PC and Xbox, Sea of Thieves currently takes more than 130 GB. The largest cut applies to 4K installs on PC and Xbox Series X: Rare says those packages should fall by at least half.
What changes on each platform
Non-4K installs of Sea of Thieves are expected to shrink by about 30 percent. On PlayStation 5 the target is also about 30 percent, so the console build lines up with the other 4K platforms after compression. Rare has not published a final size in gigabytes or a date for the public rollout.
Production director Drew Stevens said the studio has been listening to players and knows storage has become a growing burden. Sea of Thieves is now large enough that optimization is a common request, and the team has been looking for ways to compress the game without cutting content.
The cost of free space
Anyone who already has Sea of Thieves installed will need to download the game again in full. Insider players get the new package first so Rare can check whether compression causes problems before a wider release. The studio expects later Sea of Thieves patches to be smaller as well.
The “at least 60 GB” figure circulating in some outlets is an estimate based on the current size, not an official Rare number. What the studio confirmed is a goal of cutting 4K PC and Series X packages in half and other installs by about 30 percent.
Why it matters
Sea of Thieves is a live game with nearly ten years of updates, cosmetics and seasons. Each new layer pushes the installer up, and console SSD space is still scarce. A 50 percent cut on the 4K package frees tens of gigabytes, but only after a full download. Plan bandwidth and free space before the Insider build becomes the public one.
The announcement was reported by IT Home, which also notes that Rare is now managed directly by Activision after the recent Xbox reorganization. The studio did not tie that structural change to the install-size cut.
