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.

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.

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.
