Step 1: Go to the Hall of Heroes
Once you get the Exotic quest from Nimbus, head to the Hall of Heroes. This area is behind the place where you meditate to unlock more Strand abilities using Strand Meditations.
Step 2: Visit Nimbus
Go back to Nimbus to learn more.
Step 3: Defeat Vex and collect resource nodes
This next step requires you to defeat Vex to collect cipher qubits. You will also need to collect resource nodes, which are called Cloud Accretions. Just roam around Neomuna defeating Vex and grabbing the resources until its completed.
Step 4: Find the data packet in Maya’s Retreat
Now you’ll need to head to Maya’s Retreat in Liming Harbor. Track the quest to get a waypoint and to see the banner on your map. You’ll work through a canyon and out into an open plateau.
Step 5: Survive the Vex attack
When you reach the plateau, you’ll need to interact with a Vex conflux and just survive the onslaught. Keep killing Vex until the segment finishes.
Step 6: Go to Radiosonde in Liming Harbor
Head back to Liming Harbor, if you’ve unlocked the additional fast travel point in Neomuna you can zip right over. Go into the large central building that juts out along the coast and listen to the conversation between Nimbus and Osiris.
Step 7: Complete the Lost Sector in Liming Harbor
While still in Liming Harbor, go to the north side and complete the Thrilladrome Lost Sector. It’s inside the building to the north, accessed by going up into the rafters and through a vent.
Step 8: Defeat 100 enemies in Ahimsa Park
Go to Ahimsa Park and defeat enemies. Smash through 100 of them and this step will be completed.
Step 9: Head into Typhon Imperator and get the seed
You’ll now need to find a Seed of Silver Wings. There is one inside Calus’ Typhon Imperator. Head to Ahimsa Park and into the ship to locate the seed.
Step 10: Return to Nimbus
Head on back to Nimbus to talk about your discovery.
Step 11: Complete the mission, What Remains
Next is the mission, What Remains. Deterministic Chaos will unlock during this mission, so prepare to have a bit of fun. For those chasing Pinnacle drops, it could be worth holding off completing this mission until you need a bump to hit max Power.
Step 12: Go back to Nimbus
Return to Nimbus and talk about what happened.
Step 13: Go to the Hall of Heroes
The last step for Unfinished Business is to head into the Hall of Heroes.
Deterministic Chaos perks
Deterministic Chaos comes with Polygonal Rifling, Ricochet Rounds, and Composite Stock. However, you’re more interested in the Exotic perks and traits:
- Vexadecimal – While holding down the trigger, every fourth Heavy Metal projectile also makes targes volatile on impact.
- Heavy Metal – While holding down the trigger, every fourth bullet becomes a heavy projectile that weakens targets on impact.
In essence, every fourth bullet will weaken a target and every sixteenth bullet makes it volatile. This makes it quite good at spreading a lot of damage while helping your allies deal more damage.
With Unfinished Business completed, you’ll be the proud owner of Deterministic Chaos, the brand new Machine Gun added to Destiny 2 with Lightfall.

It sounds to me like every 4th round is a Heavy Metal proc, and every 4th Heavy Metal proc is a Vexidecimal proc.
So every 16th round is a Vexidecimal.
