Can I undo my spent Weapon Research Voucher or Hero Recruitment Voucher in Fortnite Save the World?

It’s not possible to reset or undo the choice of a Weapon Research Voucher or Hero Recruitment Voucher in Fortnite Save the World.

Once you unlock a weapon or recruit a Hero from the Collection Book using the voucher, that choice is permanent.

Player Support cannot refund or return these vouchers.
