"Bungie has just released The Dark Below expansion for its first-person shooter Destiny, and raiding groups are already hard at work attempting a "world first" completion.
The Dark Below contains a new Raid, called Crota's End, which replaces Vault of Glass as Destiny's hardest challenge. We won't spoil what Crota's End contains here, so watch the Twitch streams, below, at your own risk.
Established Destiny raiding groups have already mobilised. KingGothalion and crew are working their way through it now, as is StreamerHouse.
Bungie has said it will confirm the Crota's End world first completion using its User Research tools at 10am Pacific Time - that's 6pm UK time."
