SUPER SAMPLES NEED DIFFICULTY 6 PLUS
Platform
Which front
How it is delivered
Common and rare samples accumulate on their own from almost any mission. Super samples only spawn on difficulty six and above, so for most players they are not slow, they are impossible. That is why they cost more here and why the row says the requirement on its face.
Every sample a Helldiver collects goes into ship modules, and the modules are the only permanent upgrades in the game. The full unlock row exists because that is what people are actually buying samples towards, and it is cheaper as one order than as the samples plus the time.
