Super samples are an extremely scarce resource in Helldivers 2 and are only found in missions where one of the three hardest difficulties has been selected. Difficulty options scale well in Helldivers 2 and there are many of them, so deciding how much XP and currencies or what pool of resources players hope to receive from a mission is mainly what this choice boils down to. Therell be far more arduous challenges and more intimidating threats on higher difficulties, but players can weigh that against the available rewards.
