Check out our Destiny 2 Leviathan Raid Guide.
Trials of the Nine is Destiny 2’s competitive endgame activity. Trials runs during the weekend, starting Friday and ending at the weekly reset on Tuesday morning.
This week, Trials of the Nine is Survival on Dead Cliffs.

Trials of the Nine is a 4v4 activity but is not matchmade, so you will need to bring in your own four-person fireteam. Each weekend, the map and mode for Trials will rotate to present new challenges for players, but will remain the same single map and mode for the duration of the weekend so that teams can work out strategies and learn the call outs. Other teams will be doing the same, so prepare for some tough fights.
To access Trials of the Nine, players must complete the Destiny 2 campaign, finish Shaxx’s Call to Arms milestone at least one time, and be a power level of 260 or greater.
