Destiny 2 Season of the Haunted is bringing Solar 3.0 and a return to Calus's Leviathan

Season 17 of Destiny 2 is known as the Season of the Haunted, and it includes the Solar 3.0 subclass upgrade, many new Exotics, and new activities that transport us back to the original Leviathan raid, complete with Shadowkeep-style Nightmares.

Bungie revealed the new season today, just hours before its release – an uncharacteristically late disclosure and the studio's latest experiment with time and secrecy. Bungie's official product page is also up and running.

Nightmare Containment and Sever, two new activities with a terrible appearance, lead Destiny 2: Season of the Haunted. All gamers will be able to play Nightmare Containment for free, and they will be challenged to "summon the tough Nightmares and cleanse them with fire."

The whole fire-cleansing thing involves a new scythe relic that looks achingly great and comes with extra edgy armour and weaponry, including some old favourites like the Menagerie's Beloved and Austringer.

According to Bungie, Sever is related to the new season pass and allows players to explore the Leviathan's underbelly in search of "the truth behind Calus's evil plot" and "the Nightmares he governs."

Calus, Destiny 2's first final raid boss, as well as the Leviathan raid, are both returned in a huge way. Most of the raid's assets appear to have been culled from the Destiny Content Vault and blended with some recognisable faces from several expansions, doubling down on the Nightmare motif established in Shadowkeep.

Players will master the new Solar subclass trees, which have been enlarged to match Stasis and Void 3.0, as they defeat these real Nightmares.

Bungie is keeping the specifics of Solar 3.0 under wraps, but Solar was previously described as a game about burning and healing.

Within a few hours, the theory crafting community will have some botched burn builds figured out.

Arc 3.0 is set to come next season, and according to a cryptic tweet from designer Kevin Yanes, it will increase the element's agility, perhaps taking inspiration from the Season of the Risen's teleport-like abilities.

The Trespasser, a sidearm from the first Destiny, will make a comeback in Destiny 2: Season of the Haunted. It will be released alongside a new Exotic tied to the dungeon on Friday, May 27.
