History of They'll Never Know We Were There

Overview

They'll Never Know We Were There is a Season of the Seraph Triumph for completing each Heist Battlegrounds variant in under 12 minutes. Completion awards 15 Triumph score.

How to complete

Originally, complete one qualifying clear each of Heist Battleground: Europa, Heist Battleground: Moon, and Heist Battleground: Mars. Each clear needs its own time below 12 minutes; the requirement does not demand that every future run qualify.

Defeat the Deathtongue Chorister promptly to prevent Xivu Arath's battlesong from disabling abilities. During the hacking objective, protect Ghost and clear enemies that interrupt progress. At the vault entrance, split the PDT Refraction Core collection between teammates while another controls enemies, then use the cores to break the seals.

At the boss, collect and deposit Arc Charges quickly during immunity phases so the team can resume damage. Move together between objectives and minimize unnecessary combat after a route opens.

The original seasonal record became legacy progression when Season of the Seraph retired with Lightfall, although the battlegrounds continued in Vanguard Ops.
