What are White Stars?
Hades’ Star’s Description (Found in ‘About this Game’ section on Steam):
Players can organize in Corporations. Besides helping each other. Corporations can also scan for White Stars. A White Star sees up to 40 players from two Corporations battle in the same star system for Relics, a resource that can be retrieved to upgrade the Corporation and give each member additional benefits.
Time passes by very slowly in White Stars: every match lasts for 5 days, giving Corporation members time to talk and coordinate their strategy. The Time Machine can be used to plan future moves, communicate them to other Corporation members, and see potential outcomes of future combat.
