Check this. There is more spool files. There is a guide for Revelations and others that you can't get here

@ahnok it worked man, thanks a ton

Thank you for the help, you were right, I managed to unlock remaining multiplayer achievements with spoon files without altering ones I already received.

As for the dates of receiving these achievements, they will not be instantaneous, but correspond to the dates of earning by the player to whom this spool file belongs. Even if the achievement was received 10 years ago, and you bought the game only a month ago, then the date of receiving the achievement in Uplay will be 10 years ago. And in Steam, at the time of synchronization, all the achievements not received in Steam up to this point, they will all be with the current date of launch of the game.

Unfortunately, I have no advice on solving problems with this tool. I came across mentions that sometimes there are problems with Unity, but I did not find the solutions described. I can't check it myself because I don't have the game

Sorry for the long answer. I downloaded several games to check)

The method with spool files does not change the achievements already received, since their receipt is stored on the server, and the spool file is a local "intermediate" file that we replace.

But if you have not yet earned all the achievements that you planned, then they will already be earned. For this reason, it is worth using this method when you do not plan to earn the remaining achievements.

Check always the both .dll`s in the Ubisoft folder, it can happen that they are changing. In this case just copy the both again and try. So I do it and it works!

@Jack_Morn

Yes, no errors, game works normally, just the console doesn't open up when I start the game, neither from shortcut, steam or directly by ubisoft connect.

I just need it for multiplayer achievements, so I'm worried that your second guide will erase achievements I earned myself.

@Saidhe27
There may be problems with Unity, it works unstable. Wait until the game's main menu loads. No errors are displayed, just the console does not start?

Or if you're not using it for separate earning achievements can use guide below. Locked achievements will open same time

Hey Jack, in the description you said that it works with Unity too, but for me it doesn't, the console just doesn't open up like it doesn't see changed dllls, i tried to restart game, ubisoft connect, computer, download new dllls and replace them again, nothing works, even if I successfully used it with AC3R, Rogue and Black Flag. Can you help?
