Overseer Rank

Overseer rank is a leveling system in the Fallout 76 update Nuclear Winter, exclusive to the Nuclear Winter game mode.

Nuclear Winter is slated to be discontinued in September 2021. Players will be reimbursed via perk coins relative to their Overseer rank and Overseer tickets, while many of the Nuclear Winter-exclusive rewards will be implemented into Adventure mode, which will be able to be earned by completing events.

Characteristics
Instead of using the levels achieved in Adventure mode, Nuclear Winter uses a separate but similar system with each advancement being the next Overseer rank. XP is gained by competing in battle royale matches, and, as the player progresses, they are able to access more areas of Vault 51, revealing the vault's story in the process. In addition, they also receive various cosmetic rewards, including player icons and armor skins. XP and caps are also given to the player character in Adventure mode after the completion of a match.
