Alterna



Alterna is the setting of the “Return of the Mammalians” single-player campaign.

Description
Alterna was shown off during the Splatoon 3 “Return of the Mammalians” trailer and is a relatively new location. So far, we only know that it is a snowy arctic-like place where a rocket ship and portable lab are seen. Callie, Marie, and Agent 3 also appear in a couple shots.
