Borderlands 4’s new Boss Blitz Community Challenge has a straightforward target: 500,000 boss kills, collected across the community. Reaching that goal will unlock a SHiFT code granting four weapon skins.
The official announcement ties each reward’s design to a Vault Hunter.
- Troubled Upbringing — modeled after Vex
- Fresh Spray — modeled after Rafa
- Tally Them All — modeled after Amon
- Merch Line — modeled after Harlowe
Those character inspirations don’t restrict who can use the rewards. All four skins can be applied to any gun and used by all Vault Hunters, so the choice of look won’t be tied to the character it represents.
