A new mode coming in Destiny 2's Shadowkeep expansion known as Nightmare Hunt was teased at Gamescom during the Inside Xbox event. While very few details are known about Nightmare Hunt, which may be the unannounced mode Bungie teased last week, a lot of info can be garnered from the short bit of screentime the mode got in the background footage shown.
Nightmare Hunt is an activity located on the Moon, the new destination coming to Destiny 2 in Shadowkeep. It is a three-player activity that will feature multiple difficulty settings: Adept, Hero, and Legend. Each difficulty mode adds a number of modifiers. At least in this pre-release build of the expansion, Adept has one modifier, Hero has four, and Legend has six, including locked loadouts. As expected, each difficulty tier also has increasing difficulty with Adept being set at 860, Hero at 920, and Legend at the 950 level cap.
Nightmare Hunt is a matchmade activity in Adept and Hero, but matchmaking is turned off for Legend. That setup is not surprising and follows how the game handled the current Season of Opulence's Menagerie, with its Normal difficulty being matchmade and the Heroic version requiring teams to have their own fireteam before launching into the activity.
It appears that there may be different Nightmare Hunt versions with the one shown having the subtitle "Survitude." It is assumed that Nightmare Hunt will be a new mode where players will take on old Destiny bosses that have been resurrected by the Hive on the Moon in Shadowkeep. Trailers for Shadowkeep have revealed some of these bosses to include Crota from Destiny 1's Crota's End raid, Omnigul from Destiny 1's Will of Crota strike, Skolas from the original Prison of Elders also from Destiny 1, and Ghaul from the vanilla Destiny 2 campaign.
Also at Gamescom, Destiny 2 released a trailer featuring gameplay of Shadowkeep as well as a cinematic showing off the Vex, a major feature of the next raid and Season of the Undying, the season that kicks off alongside Shadowkeep.
Destiny 2: Shadowkeep releases October 1, 2019 for PC, PS4, and Xbox One, with a Stadia version also in development.
