Destiny 2’s Lightfall expansion has introduced a powerful new Exotic weapon known as the Deterministic Chaos, a Void heavy machine gun that unleashes Void debuffs on every fourth and sixteenth shot.
Players must embark on the “Unfinished Business” quest to obtain this sought-after weapon, which becomes available once you accomplish the Lightfall campaign. Here, we will delve into the step-by-step process of completing this quest, discovering Cloud Accretions, and navigating the challenges that await in Neomuna.
How to Begin the "Unfinished Business" Quest
Step 1: Initiate
To initiate the “Unfinished Business” quest, players must first complete the main storyline of the Lightfall expansion.
Upon its conclusion, head over to the Hall of Heroes, and a conversation with Nimbus will trigger the quest, setting players on another thrilling journey through the vibrant and neon-hued Neptune city of Neomuna.
Step 2: Collecting Cipher Qubits and Extracting Data
In the first phase of the quest, players must obtain cipher qubits from the Vex on Neomuna. These valuable items can be obtained by defeating Vex enemies scattered across the region.
The Vex Incursion Zone in Neomuna is a reliable spot to find high volumes of these cipher qubits. Players can get Rohan’s data from Cloud Accretions with eight cipher qubits, so forty qubits are needed.
These planetary materials are spread throughout Neomuna and can be easily located using the “Detector” Ghost mods, highlighting Cloud Accretions when players are close.
Step 3: Navigating Maya's Retreat and Facing Vex Attacks
After gathering the data, players are tasked with locating the final data packet hidden within Maya’s Retreat. Following the quest marker from Liming Harbor, players will encounter waves of enemies they must conquer before claiming the crucial data packet.
A Vex attack awaits players in Maya’s Retreat, testing their combat prowess. Defeating the enemies and recovering the data packet from the Vex Conflux is essential for progressing further in the quest.
Step 4: Regrouping in Radiosonde with Nimbus and Osiris
Players must reunite with Nimbus and Osiris at Radiosonde, found at the bottom of the Neomuna map. Following the waypoints, players navigate Liming Harbor to reach the meeting point and uncover crucial information from Rohan’s notes.
Step 5: Obtaining the Vex Compass and Creating Chaos in Ahimsa Park
The next step involves acquiring a Vex compass from the Liming Harbor’s Lost Sector. Players will venture through the Lost Sector, battling enemies to loot the chest and secure the compass.
To keep the Shadow Legion forces away from Calus’s ship, players must create chaos in Ahimsa Park. Utilizing their skills to win over combatants generates mayhem, achieving the objective and advancing the quest.
Step 6: Receiving the Seed of Silver Wings and returning to Nimbus
After causing enough chaos, players will be directed through Calus’s ship to reach a significant room. Defeating enemies will reward players with the ability to collect the Seed of Silver Wings on a wall, another crucial component to creating the passkey.
After this, players must speak again to Nimbus to create Rohan’s passkey to access the Black Garden.
Step 7: Completing the "What Remains" Mission
The penultimate step points players to the Black Garden to complete the “What Remains” mission. Nimbus tasks you to look for The Conceptual Mind and collect its memory core.
After this challenging mission full of enemies, players will be rewarded with finding the highly-coveted Deterministic Chaos Exotic Machine Gun. Return to Nimbus with their requested item to progress the questline.
Step 8: Honoring the Fallen at the Hall of Heroes
The final phase of the “Unfinished Business” quest requires players to return to the Hall of Heroes to honor Rohan’s memorial. Here, players will have a last cutscene, capping off the quest and solidifying their heroic journey.
