A friend purchased Anno 1800 on the Ubisoft store. Since Ubisoft doesn't allow gifting like Steam, I gifted him the Amusements ornaments pack on Steam. How does he activate that pack in his game?
Hello AGupwhy7,
I believe DLC content is not transferable across game launchers.
If you friend wanted to use the Amusements DLC you bought him from Steam, he would have to have own the Anno 1800 base game from Steam as well.
If he bought any DLC from Uplays Ubisoft Store, he could only use it if he bought Anno 1800 from Uplay.
Hope this clears that up for you.
