Grandmaster: Heist Battleground: Mars

Overview

Grandmaster: Heist Battleground: Mars is a Triumph in Destiny 2. It requires completing Heist Battleground: Mars on Grandmaster difficulty. Heist Battleground: Mars is one of the three Heist Battlegrounds introduced in Season of the Seraph. It is one of the six Grandmaster Nightfalls of Season of the Witch (September 26 and November 7, 2023 in that season's rotation) and also appeared in the Grandmaster rotation of Season 20, on April 18, 2023.

How to complete

1. The Heist Battlegrounds cannot be launched individually from the Director. Mars is selected through Vanguard Ops or appears as a Nightfall strike.
2. Set the difficulty to Grandmaster and complete the activity.
3. Grandmaster Heist Battlegrounds use the same rules as Heist Battleground: Europa: equipment is locked once the activity starts, radar is disabled, and defeating all Champions earns Platinum rewards that raise the drop chance for Nightfall weapons.
4. Grandmaster completions can drop Adept weapons.

Seal and reward

This triumph is one of the six Grandmaster Nightfall triumphs in the Conqueror seal. Completing all six awards Total Conquest automatically. The seal's other triumphs are Lightbearer, Breaker of Champions and Conqueror's Discipline. Completing the full seal unlocks the Conqueror title, which can be gilded once per season by completing every Grandmaster Nightfall of that season.

Availability

Grandmaster Nightfalls were removed in Update 9.0.0.1 with Destiny 2: The Edge of Fate on July 15, 2025. Nightfalls now run on a daily rotation covering all strikes and Battlegrounds, and The Portal offers Grandmaster-difficulty versions of PvE activities in their place.
