Campaign (Helldivers 2)

In Helldivers 2, a campaign is a set of Operations that are grouped together on the War Table. While some rewards are applied at the time of collection or at the end of each operation, most are affected by difficulty, and Squad Impact only gets applied upon completion of the last objective in a campaign.

After the second difficulty, campaigns have more than one operation. They can be completed in any order, but all of them must be completed for the squad impact to count.

Difficulties
Campaigns can be one of nine difficulties, from Trivial to Helldive. Each difficulty has different rewards.
