Question about uplay keys

Can't activate on steam, can't gift on this site. At least that's what the community says most of the time...

There was the time with the Assassin Creed 3 DLC keys given by Raptr which wouldn't activate on Steam but the mods still let it go because it worked with the Steam game still.

"Hello

Since Ubisoft games through Steam still use the UPlay system, all such DLC keys are still usable with winners' Steam copies of the games, which is the intent of the rule. If you know of people submitting multiple copies of the same DLC, this would be regarded as exploitative, requiring multiple accounts and denying others the opportunity of getting these items, and they should be reported. Otherwise, there is no issue. Thank you"

But otherwise, the BASE game would have to activate on Steam to be given away on this site.

You could give them away to friends (why not give someone on your Steam friends list an awesome surprise?), in a puzzle, or in some sort of giveaway using a RNG such as Random.org. What you can't do, unfortunately, is give them away via a regular Steamgifts giveaway.

Kind of you to want to share them! It's a nice looking game :)
