Alterna



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

Description
Little is known about Alterna, other than that it is a snowy arctic-like place where a rocket ship and portable lab are seen. Fuzzy Ooze appears around the area, blocking several paths. Callie, Marie, and Agent 3 also appear in a couple of shots of the location. It appears to be located inside an Octarian Dome, based on the triangles in the sky.
