A trailer for Destiny 2 Expansion I: Curse of Osiris has just been revealed by PlayStation at the Paris Games Week.

This first expansion takes players to a new destination, Mercury, where you are tasked to find Osiris, a former Vanguard and supposedly the most powerful Warlock who ever lived. Your encounter with him will give you more insight on how to defeat the Vex.

Aside from a new cinematic story, additional content include a new social destination called the Lighthouse, new missions, new strikes and raids, new free roam activities, and more.

Expansion I: Curse of Osiris will be available this December 5.
