Six galaxies rest upon the shoulders of Atlas. Now, war has come to those to peddle it.
— In-game description
Atlas HQ is the headquarters of Atlas corporation on Promethea. The current facilities stand on top of the original foundations, which were all that was left after Handsome Jack forced Atlas into bankruptcy.
Under Atlas's new CEO Rhys, Atlas HQ was rebuilt and upgraded. It now has a robust system of turrets and Atlas soldiers to defend it.
