Rare weapons are modified weapons from existing classes. During wildcard rotations of Salmon Run, one of Mr. Grizz's personal weapons will be accidentally added to the mix. Rare weapons are tweaked versions of normal weapons with much more powerful stats. These weapons are only available at certain times and can only be used within Salmon Run and cannot be used or obtained anywhere else.
