Assassin's Creed Black Flag Resynced is close enough to touch, and the last thing you want on launch day is to stare at a download progress bar while everyone else is already out on the open seas. Storage space is the boring part, but getting it wrong costs you hours. Here's everything confirmed about preloading the game and how much space to clear on each platform.
Can you preload AC Black Flag Resynced right now?
Xbox Series X|S players can preload immediately. The game has been available for preload on Xbox since late June, confirmed at 64.13 GB on that platform. PS5 preloads open on July 7, which gives PlayStation owners a short window before launch to get the download running. The PC situation is less clear-cut, with no official preload start date confirmed at the time of writing, so keep an eye on the Ubisoft store and Steam pages.

How to preload AC Black Flag Resynced step by step
The process is straightforward regardless of platform. Here's how to get it queued up:
- Head to the official Ubisoft website or open your platform's storefront directly.
- Find Assassin's Creed Black Flag Resynced and select Pre-Order.
- Choose your preferred edition (Standard, Gold, or Collector's).
- Select your platform from the available options.
- Complete the purchase through the storefront that opens.
- Once the transaction clears, look for the Download option on the product page.
- Start the download. The game will sit installed and ready until the official unlock time.
For PS5, repeat the same steps from July 7 onward. PC players on Steam or Ubisoft Connect should watch those storefronts for the preload toggle to appear closer to launch.
Pick your edition carefully
What are the file sizes for every platform?
The numbers below are confirmed across all three platforms. The spread between the smallest and largest install is only about 2.3 GB, so the platform you play on won't make a dramatic difference to your storage situation.
For context, 61 to 64 GB sits comfortably below the 100 GB installs that have become common for major action games in recent years. Black Flag Resynced is not the deepest AC game ever made in terms of sheer content volume, but it's not a light install either. Clear roughly 65 GB to be safe on any platform, accounting for minor day-one patch data.
Why does file size vary between platforms?
The difference between 61.865 GB on PS5 and 64.13 GB on Xbox comes down to how each platform compresses and packages game data. PS5 uses its own asset compression pipeline that tends to produce smaller installs compared to Xbox's packaging format. PC lands in the middle at 63.1 GB. None of these differences affect actual game content; you're getting the same game regardless of which box you play it on.

How much storage do you actually need free?
A good rule of thumb: have at least 70 GB free before starting the preload. That buffer accounts for the base install plus the day-one patch, which typically adds anywhere from a few hundred megabytes to a couple of gigabytes on top of the base file. Running the install with exactly the minimum available space risks a failed download mid-way if the patch data pushes you over the limit.
On PS5, the built-in storage sits at 825 GB usable, and modern game libraries eat through that fast. If you're tight on space, now is a good time to offload anything you haven't touched in a while. Xbox Series X owners have 802 GB usable on the internal drive, with the same advice applying.

What else should you know before launch?
Beyond storage, a few things are worth sorting out before you hit play. The day-one patch notes cover every bug fix and known issue resolved at launch, so it's worth a read if you want to know what state the game ships in. If you're still deciding which platform to buy on, the platform availability guide confirms every console and PC storefront where Resynced is available.
