According to an announcement made at the Sony Paris Games Week press briefing, Destiny 2: Curse of Osiris will be released in December 2017.
Along with the Destiny 2: Curse of Osiris release date, Sony also released a new trailer for the game’s first expansion. The expansion will focus on Osiris, as well as the planet of Mercury. It seems that the Vex will play the main antagonistic role in the expansion as the trailer refers to machines pouring through an ancient gate. The expansion will also introduce a new social space called the Lighthouse, along with new missions, Strikes and Raid content.
