An explorer meets three glowing creatures beside a workshop in a vast underground cavern.

An underground survival adventure

Gamma Critters

Dig deep. Glow wild.

Carve a home from the dark, uncover a world humming with strange energy, and befriend the little mutants who call it home.

01 The Lumen Hollows

Below the surface

The deeper you go,
the stranger it grows.

Every tunnel holds something useful, something beautiful, or something with far too many teeth. Bring a pickaxe. Leave room in your pack.

01

Break new ground

Cut your own path through forgotten ruins, crystal seams, fungal forests, and caves that have never seen daylight.

Local wildlife

Small friends.
Big mutations.

Radiation changed the underground. Somehow, it also made excellent company. Each critter has its own habits, talents, and favorite snacks.

Burrow buddy · Patient

Mossback

Slow, sturdy, and happiest with both feet in the soil. Knows a rich ore vein when it smells one.

Cave scout · Curious

Glint

A bright-eyed tunnel scout whose crystal spines begin to hum when something unusual is close.

Lantern bat · Restless

Emberwing

Equal parts campfire and chaos. Keeps dark passages bright—and carefully organized shelves less organized.

A new world is forming

Cozy enough to settle.
Wild enough to survive.
