How to Play Expunge: Styx in Destiny 2

Expunge: Styx combines platforming and combat, two of the most popular features of Destiny 2.

Expunge: Styx starts off in another Vex simulation. Your first task is to breach The Nexus. Run and jump through gaps and platforms while avoiding laser traps and falling to your death.

Expunge: Styx starts off with a platforming section. Reach the portal at the end to breach the Nexus.

There will be a portal at the end of a long corridor. Jump into it and you will be teleported inside The Nexus. This is where the similarities between Styx and Labyrinth end. Prepare for a new game mechanic!


Watch out for green-colored terminals because these will summon additional platforms that will make your life easier in Expunge: Styx. Shoot any floating Vex crystals in the area because they will drop Authentication Keys.

The Authentication Keys are an important gameplay mechanic in the Expunge: Styx mission in Destiny 2

The Authentication Keys are needed to advance throughout Expunge: Styx. Carry these with you to the Vex barrier ahead. Watch out for Vex, because you are not able to shoot back while carrying the Key.

Deposit the Authentication Keys in the designated terminals to disable Vex barriers.

Jump across platforms while avoiding laser traps and enemy fire. Speed is of the essence because you only have 10 seconds before the Authentication Key expires.

There will be several checkpoints in the Nexus where you can summon new Authentication Keys.

If you lose a Key, go to one of the small, floating white cubes around the map. These areas will produce new Authentication Keys if the one that you are holding expires.

Watch out for white checkpoints in Expunge: Styx because those will produce new Authentication Keys.

Pick up the new Key and bank it in the terminal ahead. See that giant Vex Cyclops encircled by a barrier? That is the final boss, but do not worry about it for now.

Run to the left side of the boss and you will face a large number of Vex. Ignore them or shoot through because there will be a Vex crystal at the end.

Clear the area to the left of the boss and get the Authentication Key at the far end.

The only way to unlock the crystal is to kill the Barrier Champions that will spawn shortly. Your Anti-barrier weapons will take them out easily.

Kill the Barrier Champions in Expunge: Styx to trigger the spawn of Nexus Guardians.

Once you clear the area of enemies, a Vex Harpy called a Nexus Guardian will spawn. Kill it to disable the barrier surrounding the Vex crystal. Shoot the crystals, pick up the Authentication Key, and bring it back to the terminal in the middle room.

Use Authentication Keys in to lower the protective barrier of the Vex Cyclops.

Do the same process to the right side room. This time, you will not just face Vex mobs, but plenty of laser traps as well. Watch your step if you want a flawless run! Once you deposit both Keys, prepare for the boss battle.

How to defeat Dikast the Oppressive Mind in Destiny 2

The final boss of Expunge: Styx is the Vex Cyclops called Dikast the Oppressive Mind. You need two damage phases in order to effectively delete him from The Nexus.

The boss rotates and shoots slowly, so take out the other enemies first to clear the arena. Keep damaging the boss until it hides behind a barrier and summons red laser traps around it.

Activate the second damage phase by disabling the barrier around Dikast the Oppressive Mind.

Watch out for the lasers and enemy fire. Find the Vex crystal somewhere in the room and destroy it to get the final Authentication Key for this mission.

Deposit the final Authentication Key to defeat the boss in Expunge: Styx.

Deposit the Key into the terminal at the opposite end of the room. This will make Dikast vulnerable to damage once again. Destroy the Oppressive Mind once and for all!

The end of Expunge: Styx grants you a piece of high-stat legendary seasonal armor.

Well done! You have deleted Dikast the Oppressive Mind and completed Expunge: Styx. If this is your first time, your reward is a piece of legendary seasonal armor with high stats.
