History of Iterative Loop

Iterative Loop is a Legendary Arc Fusion Rifle from Neomuna (Lightfall), a Rapid-Fire Frame that sits in the Special weapon slot. Its flavour text calls it "an antique from Neomuna's founding, given new life."

It is best known for access to Voltshot, which overcharges the weapon after a reload that follows a kill so the next hit jolts. Recommended PvE Arc builds pair it with Lead from Gold + Voltshot or Compulsive Reloader + Voltshot, and PvP builds with Under Pressure + Kickstart or Adagio. At launch it ranked last of the Neomuna weapons, as fusion rifles were seen to have little endgame PvE relevance.

Acquisition

Dropped as a reward from the Neomuna quest "From Zero…" (given by Nimbus) and as a random drop from Neomuna activities and Legendary engrams. It is craftable: collect five Deepsight copies to unlock the blueprint at the Enclave.
