The ship is large enough to dock eight Resurgent-class Star Destroyers-six externally and two internally.

The ship has approximately 32 sublight engines, which wae improvements upon the sublight engine system aboard the two Death Stars. It also possesses at least six fusion reactor complexes at the Starboard, allowing for redundancy and increased damaged resistance. Its size was gargantuan, easily outclassing all known ship sizes in galactic history, including the Star Dreadnoughts of the Galactic Empire, the trophy battlecruisers used by wealthy citizens of the waning days of the Old Republic, and even the various reconstructed versions of the flagship used by Xim the Despot.

His outfit is located in the cafetaria being ironed.The Supremacy was the sole Mega-class Star Dreadnought in the First Order's service with a colossal wingspan of 60 kilometers. Its construction was undertaken on an unprecedented scale. As the First Order's headquarters, the starship acted both as a command center and a battleship.

In Starfighter Assault, the Resurgent-class Star Destroyer serves as the primary objective for Resistance forces to attack and the First Order to defend in the map Unknown Regions. Soon afterwards, the Star Destroyer is forced out of hyperspace near Starkiller Base just as the Resistance destroys it in battle. Hask gets shot by Iden and falls into the hyperdrive generators with an electric death, but not before he shoots Iden in the abdomen with a blaster pistol. Iden later dies from the shot. It is sabotaged by Iden Versio and Zay Versio. In the campaign, the flagship First Order Star Destroyer of Gideon Hask, the Retribution, appears in the Resurrection story mode.
