Hard Mode retrofit prints
Spends limited Hard Mode entries on blueprint categories needed for ship retrofits.
Campaign → Hard Mode → a stage listing the retrofit blueprint type you need.
Limited daily activity. Entries refresh according to the game’s daily schedule, and blueprint drops are random rather than guaranteed.
Stop for the day when entries are used or the needed retrofit prints are collected; switch to a different blueprint stage when the next retrofit requires another type.
