With the release of the Vesper’s Host dungeon, Destiny 2 reached a Steam player count of over 89,000, the most concurrent players on the platform since July.

Vesper’s Host released in Contest Mode Friday at 9:30 EST, and by Friday evening Bungie announced that three fireteams had already completed the dungeon.

Bungie verified the first fireteam to complete the dungeon via Twitter, and said they would announce the second and third place fireteams next week after verification from the security team.

Shortly after the release of Vesper’s Host, the Destiny 2 team announced they were implementing mass bans for users accused of violating the game’s Terms of Service. It is unclear how many players the mass banning affected, although it is not an unusual procedure for a live service game at the beginning of an event.

The new dungeon has received mostly positive reviews online, with players praising the challenging difficulty.
