The first expansion for Destiny 2 is called Curse of Osiris, and it takes the game's FPS action to Mercury.

A listing for the expansion is already up on the Microsoft Store, and it promises new story missions and adventures set on Mercury.

"Journey through time and space to learn the secrets of Osiris, avert a dark future, and rebuild the ties between the legendary Warlock and his greatest student – Ikora Rey," the listing reads.

There's also talk of a "mysterious Infinite Forest"; new themed weapons, armour, and gear; and new competitive activities and multiplayer arenas.

There's no mention of a release date.

In the meantime, Destiny 2's first raid opens on Wednesday. Once we best that, we'll look at publishing our review of the game.

Bungie has also released this roadmap for the game's first month:

Destiny 2's first DLC will send players closer to the sun

On launch day, Destiny 2 had more than 1.2 million concurrent players online, and it's not even out on PC until October 24.

However, there are some teething issues: some players on PlayStation 4 are experiencing crashes, while others are missing out on a reward for a certain quest. Bungie is looking into both problems.
