Beyond Light has arrived, and Trials of Osiris will hopefully return today after a three-week hiatus.
A "recently discovered issue" meant it was gone for a couple of weeks, but as far as we know, it's back.
If you're new to Destiny 2, we've got everything you need to know about the mode below.
What Is Trials of Osiris?
Trials of Osiris is the game's highest tier PvP content. Teams duke it out in an elimination-style match, and do their best to get to Flawless - that's a seven-game win streak.
Players can lose a match or two, but any more will see them ejected - but the mode offers some great rewards.
Don't forget that Trials of Osiris is a weekend-only activity, so you won't be able to play if after weekly reset on Tuesday.
In terms of lore, one popular fan theory is that the lighthouse featured in the mode is actually drawing the Darkness nearer - setting up the events of Beyond Light.
