You've probably seen the countdowns, the leaked patch sizes, and that one guy in your Discord server who won't stop talking about the "end of an era." It’s a lot. Honestly, the shift from standard Rainbow Six Siege to Siege X is the biggest thing to happen to the franchise since it launched back in 2015. But if you're sitting there asking what time is Siege X coming out, the answer is actually already written in the history books—because Siege X isn't a future "sequel" in the traditional sense. It's already here, having officially rolled out on June 10, 2025.
If you're looking for the next big milestone or wondering why your game just rebranded itself, you're likely looking for the Year 11 Season 1 launch or the upcoming Operation Tenfold Pursuit.
The 2025 launch of Siege X was a global "synchronous" event. Ubisoft didn't just flip a switch; they brought the whole house down for maintenance first. Most players saw the update go live around 10:00 AM EDT, but depending on where you were standing on the planet, that could have been 7:00 AM in Los Angeles or a midnight launch on June 11th for the crew in Sydney.
The Siege X Launch: When the Servers Actually Went Live
Let's look at how Ubisoft handled the "X" evolution. It wasn't just a patch; it was a total overhaul of the game's foundation. They called it the "major evolution" and tied it directly to Operation Daybreak.
Maintenance usually takes about 60 to 90 minutes, assuming the hamsters running the servers are well-fed. During the Siege X launch, the schedule looked like this:

- CEST (Berlin): 4:00 PM
- JST (Tokyo): 11:00 PM
If you are reading this in early 2026, you are likely waiting for the next seasonal shift. Ubisoft has settled into a very predictable rhythm. New seasons for Siege X generally drop on Tuesdays. If the pattern for Year 11 holds, we are looking at a March 2026 window for the next major content drop.
Why Everyone Is Still Confused About the Release
Part of the confusion stems from the name. "Siege X" sounds like a brand-new game you'd find on a shelf. In reality, it was a "CS2-style" move. Ubisoft replaced the existing Rainbow Six Siege client with the Siege X version. You didn't have to buy a new game, but you did have to download a massive patch—we're talking 51.9 GB on Ubisoft Connect and over 57 GB for the Xbox Series X|S.
The game also went free-to-access. This was a huge pivot. Suddenly, anyone could jump into Quick Play or the new Dual Front mode without dropping forty bucks. But, and this is a big "but," if you want to play Ranked or the Siege Cup, you still have to hit level 50 or upgrade to the premium editions.
What You Get Right Now in Siege X
The "X" era brought a few things that changed the literal feel of the game:
- Dual Front: This is the 6v6 mode everyone was screaming about. It has respawns. It's on a massive map called "District." It feels less like traditional Siege and more like a tactical arena shooter.
- Audio Overhaul: They finally fixed (or tried to fix) how sound travels through walls and floors.
- Visual Modernization: Maps like Clubhouse and Chalet got 4K textures and new lighting. It looks crisp.
- R6 ShieldGuard: This is the unified anti-cheat. It's meant to be "live," meaning they can update security without taking the servers down for four hours.
Is Siege X Coming to Mobile?
This is where people get their wires crossed. There is Rainbow Six Mobile, and then there is Siege X. They are not the same thing. Siege X is the PC and console powerhouse. While you can play Siege X via cloud services like Amazon Luna on your phone, the actual "Mobile" game is a separate beast with its own roadmap.
If you're waiting for Siege X features to hit the mobile app, you're going to be waiting a while. Ubisoft has kept the development teams mostly separate to ensure the "core" tactical experience doesn't get watered down by mobile hardware limitations. Speaking of hardware, if you're still on a PlayStation 4 or Xbox One, you can play Siege X, but you can't play the Dual Front mode. It’s simply too much for those old consoles to handle.
What to Do If Your Update Isn't Showing Up
If it's Tuesday and a new season is supposed to be out, but your launcher is sitting there doing nothing, don't panic.
First, check the official Ubisoft Support Twitter (or X, whatever we're calling it now). They are usually pretty quick to announce if maintenance is running long. Second, try restarting your client. Steam is notorious for "forgetting" to check for updates until you force its hand.
Third, make sure you have the space. These Siege X updates are beefy. If you're running a 256GB SSD, that 90GB "Ultra HD" texture pack is going to hurt.
Actionable Next Steps for Operators
Stop waiting for a "new" game and start optimizing the one you have.
- Check your HDD/SSD space: Clear at least 100GB to account for the patch and the temporary files needed during installation.
- Verify your Account: If you played the original Siege between 2015 and 2024, log in now to claim your Veteran Rewards. You get a badge based on your "Year of Arrival" and some exclusive skins.
- Download the HD Textures: If you're on PC or a next-gen console, go into the "Manage DLC" settings. The 4K textures make a world of difference on the modernized maps.
- Re-learn Rappel: The new "Advanced Rappel" system allows for horizontal sprinting. It changes how you peak windows entirely, so jump into a Training Grounds match to get the muscle memory down.
The "X" in Siege X stands for ten years of history, but the game is moving faster than ever. Get your settings dialed in now, because the Year 11 meta is going to be a wild ride.
