The Assassins Creed: Unity trainer worked for UPlay despite being made with the Steam version so maybe the opposite is true here, in any case it's still going to need a update since they have the 1.1.0 patch cued up for Monday just before the game gets released and then a 1.2.0 patch sometime after that.
(Both with several important fixes, just as with AC: Unity.)
EDIT: Steam announcement regarding patch 1.1.0, it's a bit more detailed than the UPlay readme.txt file.
LinkAnd the patch info from said readme. (Game itself, despite this, is still only version 1.0.0 though, again much like how it was for Unity which is kinda odd.)
