The Vex flock from the Black Garden and only the traveler knows why. In this guide, we're going to show you how to kick off the Vex Offensive, the new content that just arrived in Destiny 2.
Destiny 2 - How to start the Vex Offensive
The first step to starting Vex's offensive is to visit Ikora in the tower. She will give you an item called Vex Invasion Emergent Protocol, which will task you with killing Vex on the Moon and defeating Gate Lords.
It gets a little confusing because when you click on Vex Offensive on the Moon map, there is nothing you can do. It will tell you to complete "Eyes on the Moon" instead.
What you need to do is go patrolling the moon. You may have noticed three Vex head symbols since Shadowkeep launched. You will see them marked in the red boxes above. These areas show that the Vex are trying to invade. Think of them as a version of public events. When we start, you will have to fight a huge wave of Vex and eliminate a Lord of the Gates. Do this three times to complete the Vex Invasion Emergent protocol challenge and continue with the Vex Offensive.
Invasions seem to be tied to public timings, so if you see an active public event marker just perform the ES, then wait a few minutes and the invasion should happen.
They won't always be active, but you should notice that a small amount of Vex enemies now spawn while you're on patrol. Just keep doing circuits on the Moon until one of the hotspots becomes active. You won't be able to miss it, as a huge ball of energy hangs in the sky as the Vex sets in.
Once you've done that and completed the item challenge, head over to Eris Morn. After speaking with her, you will be able to initiate the Director's Vex Offensive.
Update: If you can't get the item from Ikora, or Eris Morn is clumsy, reports are coming to us just to have your game restarted, which should be fine with you.
