Destiny 2 will debut its first weekend of Trials of the Nine, the new endgame PvP event, which will appear every weekend from 10 a.m. Friday morning PDT to the next weekly reset. The day before the first Trials of the Nine event in Destiny 2, developer Bungie has released a teaser trailer. It’s an extremely brief teaser for the mode, the details of which Bungie is still keeping a secret.

The short teaser trailer features a set of three symbols — and a little more — which will be discussed more below. But for now, here is the teaser:

Fans may recognize the three symbols that appear to be the logo for Trials of the Nine, as they were the logos that game director Luke Smith wore on his second hoodie during the Destiny 2 Reveal Event in May 2017 (the first hoodie featured the logo for the Leviathan raid, which debuted earlier this week).

Trials of the Nine replaces Destiny 1‘s Trials of Osiris. Whereas Trials of Osiris was a 3v3 Elimination mode, Trials of the Nine will be 4v4 just like every other PvP mode in Destiny 2. While not all the rules and details of the new Trials of the Nine are known, Bungie did confirm that (at least for September), the event will alternate between the Countdown and Survival game modes.

Based on the clan rewards that have been added to Destiny 2, players of a clan will need a 7-win card in order to earn the corresponding weekly reward for their clanmates. That may suggest that Trials of the Nine will only require seven wins instead of the nine that Trials of Osiris did, but players will have to wait until tomorrow to find out for sure.

There definitely looks like there will be more new things to learn for Trials of the Nine outside of it just being a 4v4 mode. In its weekly blog, Bungie told fans “You have a new ritual to learn” suggesting some significant changes from Trials of Osiris.

The last point of note in the teaser, is a quick flash that shows a mysterious shadowy figure.

Could it be Osiris, the Warlock who was behind Destiny 1‘s Trials of Osiris and the focus of Destiny 2‘s first expansion Curse of Osiris? Or is it a member of the Nine, the mysterious group spoken of in Destiny lore? Perhaps some of these questions will be answered with the debut of Trials of the Nine tomorrow September 15 at 10 a.m. PDT.

Destiny 2 is available now for PS4 and Xbox One, and on October 24, 2017 for PC.
