It’s like a raid, but it’s not as much of a time investment as a raid, but it does have the same loot as a raid, but it’s not actually a raid-raid. It’s a raid lair. It’s the same, but different.

So that’s kind of confusing, but according to new info revealed in Bungie’s Curse of Osiris livestream last night, it’s what we’re getting instead of a new raid. The first raid lair – Leviathan, Eater of Worlds – is a sort of expansion of the original Leviathan raid, featuring totally new stuff.

“A raid lair is a brand-new six-player raid activity,” explained senior game designer Brendan Thorne. “It’s an entirely new set of encounters, new puzzles, new loot, completely new places to explore […] and then we have a brand-new final boss for you to fight.” He also added that “you’re gonna die a lot”, but that’s not so new.

Besides the raid lair and “the most notorious Guardian in Vanguard history“, the DLC also debuts the new Plains of Glass and subterranean Infinite Forest destinations on Mercury, which has been occupied and given a shiny, creepy makeover by the Vex. The Plains of Glass is a standard-issue zone with patrols and public events and whatever, while the… infinitely more intriguing Infinite Forest is “a reality engine the Vex use to simulate all of the aspects of reality that they can touch”, and exists in the past, present, and future for maximum replay diversity. Oooooh.

“We can create new and unique experiences every time you come into the Infinite Forest,” said art director Dave Matthews. The point, apparently, is to “create something that felt like it could sit outside of time and space.”

You know, like that one sock in your laundry.

Curse of Osiris is out on 5 December on PC, PS4, and Xbox One.
