Assassin's Creed Unity Patch 4 mishap results in 40GB download for Xbox One

Ubisoft has released the fourth patch for Assassin's Creed Unity, although an issue has come up for Xbox One owners of the game.


Ubisoft delayed Assassin’s Creed Unity’s fourth major patch earlier this week, but today, the publisher has announced it has rolled out the patch on both PlayStation 4 and Xbox One. PC players, unfortunately, won’t be receiving the patch until later this week.

The patch weighs in at a hefty 6.7GB and includes frame rate enhancements, which the team needed to replace and update portions of the Paris city map where they were seeing issues arise the most. Stability improvements, improvements to gameplay, and online fixes are also included in today’s patch. Ubisoft has supplied the full patch notes for its fourth major patch, which you can check out at the end of this story.

Unfortunately, today’s update hasn’t gone without a hitch as Xbox One users who have previously applied Patch 3 are being met with a 40GB download instead of the 6.7GB one. Ubisoft reports an issue with the patch downloading process has resulted in the entire game being replaced instead of just the parts that are affected by the patch. “This is obviously not the expected behavior, and we apologize that many of you will have to wait longer than expected to complete this download,” Ubisoft writes. “This issue isn’t causing any other problems and once the download is completed players will have the most-up-to-date and fully patched version of Assassin’s Creed Unity.”

Ubisoft is working with Microsoft at this moment in order to find a solution to this issue, although it doesn't have an ETA as to when a fix will be implemented. For the time being, Ubisoft has a solution for those who own the disc version of Unity. All you'll need to do is uninstall and reinstall the game, which will allow you to just download the 6.7GB patch instead of the larger 40GB download.

Here's the full patch notes, as promised:

      "...we apologize that many of you will have to wait longer than expected to complete this download..."

      Umm, Ubisoft, I think that the time spent on the update download will not be foremost on the mind of customers who have monthly bandwidth caps.

        This was my thought as well. Luckily I don't have data caps. Praying that TWC and Comcast merger-atempt dies a quick and painful death.

      due to some unforeseen events, my home internet is metered cellular, I've managed to get the highest data cap available (for a reasonable price) , and that is 50Gb/mo. If I got this download, well... that was almost my entire data cap for an entire month.. thank you Ubi, kisses and hugs

        What happens if you call your ISP and tell them that you "made the mistake" of buying an Xbox One, Assassin's Creed Unity, and leaving the Xbox One on standby to automatically download patches? I don't know what the chances are of a credit for this, but I imagine other customers in the same boat will be really mad. Even though it's not the ISP's fault, we're going to run into more situations like this, now that current-gen consoles automatically download updates when they're on standby, and game publishers still don't seem to appreciate that they have customers who have metered Internet, AND are ultimately forced to download gigantic title updates in order to continue using multiplayer, as well as fix game-breaking bugs (of which AssUnit has no shortage).

        Yeah all this digital distribution flies right into the face of how isps want to meter the internet. Next 5 years are going to be interesting what precedents are set

          Metered in general is borderline fraud. There is so much data you cant control anymore, phones autoupdates, tablet autoupdates, windows autouodates, consoles autoupdates, this is not including normal digital downloads that has swelled in size enourmously

            Metered is fine as long as it's fully metered for a low cost, meaning all the grandmas who just check email would be paying like 50 cents a month.

            A large minimum charge PLUS metering is where it gets fraudy IMO.

            It wouldn't be a problem if there was competition though.

      They should do a GOTY edition that lets you switch between the patches so you can play with the various states of broken-ness this game is going through on it's way to becoming a real boy...same with MCC

        I'm betting that within a month or so we won't hear anything else about patches, regardless of how much work still needs to be done. They'll post about there being a lot more work needing to be done or something and that'll it'll be a bit before we see a patch, then they'll go radio silent. Then at E3 they announce the next game and that's it.

            Announced is a bit of an overstatement. The name and plot were leaked and Ubisoft was pretty unhappy about it iirc. I'm not sure if they actually officially announced it after that or not.

          That's what I would expect. They're on an annual release schedule so any time spent fixing a game that already shipped is time not working towards the next release.

      So redownload the game?

      I wonder which AC team this was and was it a new team? It's not like they have had problems like this before.

        I dunno, it was at least playable for most people. Halo MCC multiplayer was flat broken for the longest time. Also apparently Halo 2 doesn't have autosave still? They may have fixed that, not sure.
