Is Endurance the campaign hub?
Endurance is the surviving carrier where the player is rescued and where important first-person intermission scenes take place.
Confirmed explanation
It functions as the narrative base for the desperate FCU force and helps connect missions, command pressure and squad relationships. This is not confirmation of a freely explorable hub with upgrades or side quests.
What is not confirmed yet
Movement freedom, optional conversations and ship-management systems remain unannounced.
