How to get Deterministic Chaos in Destiny 2: Lightfall

Lot 2‘s Lighting expansion introduces a fantastic new exotic weapon: Deterministic chaos.

Deterministic Chaos is a Void heavy machine gun that shoots Void debuffs on every fourth and sixteenth shot. You can unlock deterministic chaos through the “Unfinished business” Quest, which becomes available after you get the Lighting campaign. This quest takes you through Neomuna – the neon-colored Neptune city that makes up most of Lighting‘s campaign – to find pieces of data needed to eventually complete a mission in the area of ​​the Garden of Salvation attack.

In this Lot 2 guide, we’ll cover how to unlock the Deterministic Chaos heavy machine gun, how to find Cloud Accretions, and how to navigate the “Unfinished Business” quest.

How to start ‘Unfinished Business’ in Destiny 2

You can start the quest “Unfinished Business” by completing the main Lighting campaign. Once completed, you’ll be prompted to talk to Nimbus, and they’ll give you the quest.

How to get deterministic mayhem in Destiny 2

The steps to the Deterministic chaos in Lot 2 are as follows:

1. Visit the Hall of Heros on Neomuna. This quest will open that area at the top of the map.
2. After watching the cutscene, go to Nimbus to find out why they left Rohan’s induction ceremony early.
3. Collect coded qubits from the Vex and use them to extract Rohan’s data from Cloud Accretions in Neomuna.
4. Find the last data packet in Maya’s Retreat.
5. Survive the Vex attack in Maya’s Retreat and recover the data packet from their Conflux.
6. Regroup with Numbus and Osiris in Radiosonde to find out what was in Rohan’s notes.
7. Get a Vex Compass from the Lost Sector in Liming Harbor.
8. Create chaos in Ahimsa Park to lure Shadow Legion troops away from Calus’ ship. The more you use your skills to defeat combatants, the more mayhem you create.
9. The other part of the access key is a Seed of Silver Wings. One can be found in Calus’ treasure deep within the Typhon Imperator.
10. Return to Nimbus in Striders’ Gate to build a key.
11. Complete the “What’s Left” mission.
12. Bring the memory core of the conceptual mind to Nimbus in Striders’ Gate.
13. Go to the Hall of Heroes to honor those who shortened their years for the sake of humanity.

Aside from some combat-heavy segments, “Unfinished Business” is pretty straightforward overall. (The recommended power level for the last mission of the quest is 1770, so be sure to prepare.) But there are some quest steps that are a bit more complicated. Let’s break them down.

Where to find Cloud Accretions in Destiny 2

Cloud Accretions are the planetary material for Neomuna. They can be found all over Neomuna, but if you put on one of the “Detector” Ghost mods, they will be highlighted when you get within range of one.

Collect cipher qubits from the Vex

During this quest, every Vex you kill on Neomuna has a chance to drop a ‘cipher qubit’. There are plenty of them in the Vex Incursion Zone, revolving around the Neomuna map on a weekly basis. (You can find it on your map.) Once you’ve collected eight cipher qubits, found a Cloud Accretion, and collected it, you’ll be given one of five resources to extract.

Finding the last package in Maya’s Retreat

If you follow this quest, the game will lead you to Maya’s retreat. Follow the path that starts in Liming Harbor and reach the area. You will encounter a few waves of enemies that you must kill before you get the final pack.

Regroup with Nimbus and Osiris in Radiosonde

You can find the Radiosonde at the bottom of the Neomuna map. Go to Liming Harbor and make your way through the structure.

Finding the seed of Silver Wings

After defeating enough enemies in Ahimsa Park, the game will guide you through Calus’ ship. This is a similar path during the campaign, so make your way through it. You will enter a large room where you must activate two plates and defeat enemies before you get the Seed of Silver Wings.

Completion of the mission “What remains”

This mission takes you through the Garden of Salvation raid, but backwards. At the end you get the Deterministic Chaos weapon.
