History of Worldline Catalyst

Overview

Worldline Catalyst records completion of the Worldline Zero catalyst. Worldline Zero is an Exotic Arc Sword, rather than a Hand Cannon. Obtain the catalyst, defeat 300 combatants with the sword, then apply the upgrade.

How to complete

The catalyst can drop through sword combatant kills. Once it is acquired, use Worldline Zero against groups of weak enemies and keep Heavy ammo available for powered attacks. Land the finishing blows with the sword; progress carries across activities. Apply the catalyst in the inspection screen after the 300-kill objective is complete.

The upgrade grants Another Dimension, improving Tesseract activation. The old requirement to strike five different Escalation Protocol bosses was replaced in Season of the Chosen. That five-week Mars route is obsolete and is unnecessary for the current catalyst-completion record.
