To download Siege X on PC, open Ubisoft Connect, Steam, or the Epic Games Store, search for “Rainbow Six Siege,” and choose the new Free Access option or your existing library copy.
Technically it’s the same game you’ve installed before — if you already own Rainbow Six Siege, Siege X dropped into your existing library as a massive free update on June 10, 2025. If you’re new or coming back, how to download Siege X on PC depends on which storefront you use, and whether you want the new Permanent Free Access version or the full paid upgrade. All three PC storefronts deliver the same updated game with the new 6v6 Dual Front mode, enhanced audio, and a visual overhaul — the only difference is where your account library lives.
Downloading Siege X on PC: The Three Routes That Work
Getting Siege X on your PC is a matter of choosing between Ubisoft Connect, Steam, or the Epic Games Store. All three deliver the same game and the same June 2025 update, but the exact steps differ slightly. New players should start with the Free Access model, which unlocks Quick Match, Unranked, and Dual Front at no cost.
Ubisoft Connect (Best for Free Access)
This is the primary storefront for Siege X’s Permanent Free Access. Existing PC players have likely already used this launcher for Rainbow Six Siege.
- Open Ubisoft Connect PC and sign in to your Ubisoft account.
- Search for “Rainbow Six Siege X” or “Tom Clancy’s Rainbow Six Siege.”
- On the game’s page, select Play Now or Download to start the installation. New players should use the official Ubisoft Siege X Free Access page as the canonical entry point.
Steam (Best for Existing Steam Libraries)
If you already own Rainbow Six Siege on Steam, the Siege X update is already in your library. New players can also claim Free Access through Steam.
- Open the Steam client and sign in.
- Search for “Tom Clancy’s Rainbow Six Siege” in the store or your library.
- Click Play Now on the store page or Install on the library page. The game will update to Siege X automatically.
Epic Games Store (Alternative Free Access)
Epic also offers the Free Access version of Siege X. The process mirrors the other launchers.
- Open the Epic Games Store launcher.
- Search for “Rainbow Six Siege – Free Access.”
- Select Download and follow the store’s installation flow. Confirm platform availability for your region before installing.
A Ubisoft account is required regardless of the storefront you choose, and linking it is handled automatically during the first launch.

Can Your PC Run Siege X? The 2025 System Requirements
Siege X raises the hardware bar significantly compared to the original Siege, so checking your specs before downloading is essential. Ubisoft has published four official presets covering everything from 1080p at 60 FPS to 4K at 120 FPS. If your PC doesn’t meet the Low preset, the game may not run at all.
| Preset | Resolution & FPS | CPU | GPU | RAM | Storage |
|---|---|---|---|---|---|
| Low | 1080p @ 60 FPS | Intel i3-8100 / AMD Ryzen 3 3100 | NVIDIA GTX 1650 4GB / AMD RX 5500 XT 4GB / Intel Arc A380 6GB | 8 GB | 65 GB SSD |
| Medium | 1080p @ 60 FPS | AMD Ryzen 5 3600 | NVIDIA RTX 2060 / AMD RX 6600 | 16 GB | 65 GB SSD |
| High | 1440p @ 120 FPS | Intel i5-11600K / AMD Ryzen 7 3700X | NVIDIA RTX 3070 / AMD RX 6700 XT | 16 GB | 65 GB SSD |
| Ultra | 4K @ 120 FPS | Intel i5-11600K / AMD Ryzen 5 5600X | NVIDIA RTX 4070 Ti Super / AMD RX 7900 XT | 16 GB | 110 GB SSD |
Windows 10 or 11 (64-bit) and a DirectX 12-compatible GPU with Shader Model 6.0 are required across all presets. The Ultra preset is the only one that needs over 65 GB of storage space, so check your available drive space before starting the download.
Common Pitfalls When Installing Siege X on PC
Most installation problems come from platform confusion or outdated hardware assumptions. A few things to watch for:
- Mistaking the update for a separate product: Ubisoft’s store listing still uses the base-game name “Rainbow Six Siege.” The “Siege X” branding covers the June 2025 update — you don’t need to find a separate product page.
- Downloading from unofficial sources: YouTube walkthroughs or third-party guides may show outdated steps. Always start from the official Ubisoft, Steam, or Epic store pages.
- Platform confusion: The Siege X Test Server is PC-exclusive and requires owning the game and registering separately. It is not the normal live game download, so skip it unless you specifically want to test upcoming features.
- Assuming old PCs work unchanged: The system requirements for Siege X are substantially higher than the original Siege’s specs. A PC that barely ran the 2020 version will likely struggle or fail to launch Siege X.
Your Siege X Installation Checklist
To avoid wasted downloads and launch-day frustration, run through this quick triple-check:
- Confirm your specs. Match your CPU, GPU, and RAM against the Low preset in the table above. If you don’t meet it, the download will be wasted disk space.
- Pick a storefront. If you’re new, go with Ubisoft Connect directly to skip the extra account linking. If your library is on Steam or Epic, use those.
- Free up disk space. You need 65–110 GB on an SSD. A near-full HDD may cause stuttering even if the installation succeeds. You’ll know the download worked when your library shows the “Play” button active and the full game client launches past the title screen.
