Alterna



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

Description
Little is known about Alterna, other than that it is a snowy Arctic-like place where a rocket ship, statues resembling the moai of Easter Island and portable lab are seen. Fuzzy Ooze appears around the area, blocking several paths. In the single-player mode, the New Squidbeak Splatoon, consisting of Callie, Marie, the Captain, Craig Cuttlefish, and Agent 3, are all present in the location. It appears to be located inside an Octarian dome or similar location, based on the triangles in the sky.

Quotes
"Squid Research Lab here reaching out for a little help! We've identified several mysterious structures in the space known as Alterna. They're not complete, so we can't identify them. And when science falls short, scientists turn to... Twitter? Can you help us with these?"

"Several mysterious structures have been identified in the space known as Alterna. They look as if they’ve been modelled after something, but they're all incomplete. What could be their significance?"
