The Front Lines

Overview

The Front Lines is a Vex Offensive Triumph associated with the Undying seal from Season of the Undying. It advances by completing encounters and closing the warp gate, with successful encounters providing the most efficient progress. The original activity was removed when Season of Dawn began, so this seasonal Triumph is no longer obtainable through its original route.

Original completion method

Complete full Vex Offensive runs in the Black Garden. Clear the Vex waves in each opening area, defeat Gate Technicians and pick up their Void Craniums. Fire the relic beams at the floating Oracles to finish the encounter objectives.

At the final gate, use more Void Craniums to remove Crotheon, Gate Keeper's shield, then damage the boss. Repeat the shield and damage sequence until it dies and the gate closes. The Final Assault version used The Undying Mind instead. Finish encounters successfully and stay through the boss defeat to obtain the run's completion progress.
