Destiny 2 DLC Curse of Osiris guide and walkthrough: Everything added in the Mercury-set expansion

Destiny 2 Curse of Osiris DLC is the first major expansion to Bungie's space-faring sequel.

Curse of Osiris introduces a variety of new modes and places to explore, and while understandably not as meaty as larger yearly updates such as The Taken King and Rise of Iron, it does feel to offer more variety than the smaller expansions offered in Destiny's first year.

What's included in Destiny 2 expansion Curse of Osiris?

The game's first major expansion adds the following features:

• New story missions and quest centered around Warlock Osiris
• New Patrol space on Mercury and Lighthouse social setting
• New Mercury Heroic Public Event, Lost Sector, Lighthouse secret chest
• Heroic Strike Playlist, with a new Milestone offering Powerful Gear
• Heroic Adventures on Mercury, available once you complete the main story
• New weapon quests named Lost Prophecy Verses once the story is complete
• New content to the Leviathan Raid, named the 'Raid Lair'
• New Crucible map Wormhaven on PlayStation
• Increased max level cap to 330 / 335
• New Exotic weapons and armour

As well as the above, a quality of life patch is also tweaking and amending other aspects of the game, even if you aren't purchasing the expansion.

• Unlockable Armour Ornaments
• A new weekly reset time
• Ability to buy Mods direct from Banshee-44
• You no longer need to complete the Leviathan Raid before you can spend your Calus Tokens
• New Clan Banner rewards as the game enters Season 2

What else you need to know about Destiny 2 DLC Curse of Osiris?

In further detail, here's what we know:

A new world quest featuring Osiris

Described as a "all-new cinematic story with new and returning characters" by Activision, the expansion sees female Ghost Sagira voiced by Firefly and Homeland's Morena Baccarin) separated from Osiris.

Ikora - of which Osiris was her mentor - will have a big focus in the expansion, as well as the Vex, who have been up to something throughout time and space. Maybe we'll find out what.

New Patrol space and 'dungeon' area the Infinite Forest on Mercury

Described as "a simulated reality in the middle of time, controlled by the Vex", this new area is where players will be exploring as part of the storyline and several post-story Adventures, as well as Mercury as a Patrol space and small social space.

The Infinite Forest in particular is a shifting location which will be explored in greater detail through Adventures, with defined start and end points and a random assortment of "intelligently designed" sections in the middle, each featuring a different enemy race and themed setting.

You can see more on this in Bungie's second livestream on the DLC:

New social space, The Lighthouse

Mercury was a destination in the first Destiny, as part of Trials of Osiris social space the Lighthouse, which is a small area in the Mercury Patrol space. It's here you can collect the Lighthouse secret chest and unlock Lost Prophecy Verses.

New missions, new Strikes and free roam activities

There are three Adventures and two Strikes - first introduced as story missions in the DLC, then added to the playlist - topping up the handful available in the main game, including the return of a Heroic Strike Playlist.

The Mercury Patrol space, meanwhile, will have one new Lost Sector, region chests and new Mercury public event 'Vex Crossroads'.

New weapon quests named 'Lost Prophecies'

Once the story is over, you'll have access to 11 quests named 'Lost Prophecies'. These are mini-quests that require you to collect drops as you play certain activities, such as Public Events and Heroic Adventures. Once you have fulfilled them, you then return to an altar in the Lighthouse social space, turning them in to receive Vex-themed weapons.

You can see more about this at the start of this video by Arekkz:

New Raid content

Bungie will add additional locations to the Leviathan Raid as part of a new feature known as a 'Raid Lair'.

The 'Eater of Worlds' activity will have new areas, puzzles, a new boss fight and a higher level requirement of 300. It won't be as long as the existing Raid, but it will have its own rewards, including guns, armour and cosmetics.

Though it will be set on new parts of the Leviathan, it'll be a separate option on the Director,.and you won't need to have finished the original Raid to attempt it.

Bungie added there will be a second Raid Lair for the game's second expansion - also set on the Leviathan - sometime next year.

A tantalising addition is new Raid content, but what this means exactly is unknown. It could be anything from a new Raid - which is possible, if the original's The Dark Below expansion is anything to by - or a remix or addition to the current Leviathan Raid.

New Crucible map Wormhaven

Sony confirmed a PlayStation exclusive Crucible map set in Titan's New Pacific Archology area would come with the expansion. As with other platform-exclusive content, expect it to arrive on other platforms eventually - though not anytime soon.

New level cap

The expansion will raise the Destiny 2 level cap, from character level 20 to 25, and the Power Level 305 to 330 (or 335 with mods). What exact activities will take you there is unknown, but it'll likely be from the same 'powerful gear' Engram activities we've seen so far.

Season of the Haunted is here! Get up to speed with our levelling guide. For The Witch Queen, learn how to get Exotics including Dead Messenger and Parasite. Late last year, we saw the Bungie 30th Anniversary, which adds the Grasp of Avarice dungeon, Strange Coins and new Exotics, including the Gjallarhorn and Forerunner.

New weapons, emotes and other additions

As well as new areas and maps, there's also a few other smaller additions. For one, there is a new 'Selfie' emote, and it's pretty special:

There are new weapons, one of each seemingly wielding by Osiris himself - Gamer Network's Arekkz believes it could be an Exotic Auto Rifle. Also shown is returning Exotic Jade Rabbit and possibly even Telesto:

The above video also highlights new armour pieces, likely gained from new end-game activities introduced in the expansion.

That's all we know so far. Bungie will surely trickle more information out about the expansion in weeks leading into release, and we'll be updating this page when that happens.
