Tangled Shore is where the first Expunge mission takes place. You’ll be taken inside the Vex network in no time if you open the Director and pick Expunge: Labyrinth.
You’ll be given the mission ‘Breach the Nexus’ after booting in, and you can now enter the network and follow your objective marker.
As you progress through the Vex maze, it will shift and evolve, revealing new places. Keep an eye out for any new passages that surface.
Mithrax will contact you with a warning: the Vex are attempting to purge you from the network.
An ominous rumbling noise will be heard, and a bright Vex grid will materialize from where you came. You’ll have to outrun the purge now or else you will be eliminated.
Continue forward as fast as you can until you reach a little Vex portal, which will teleport you to a new platforming section.
Keep an eye out for any Vex constructs that you can blast to open the path, then carefully navigate your way across these platforms to continue.
After beating an enemy who drops a Data Spike, the curveball will appear. Pick up this bright Vex orb and carry it until you reach a terminal and are required to deposit the data, at which point you will be able to proceed.
Fantis, the Oppressive Mind, will eventually arrive and attack. The Vex will become shielded and immune to your attacks after causing damage to Fantis.
Locate and destroy two enemies who will drop Data Spikes, which you’ll need to place in the respective terminals to break the shield.
Hit the Vex with everything you’ve got once the Oppressive Mind is vulnerable again.
When you defeat him, you’ll receive some loot, seasonal currency, and the Expunge: Labyrinth mission will be completed.
