An Atropion colony at dusk: command center, extractors, silos and turrets on volcanic rock, soldiers and a hover tank in front

One loop, endless frontier

Harvest

Extractors run on your schedule — 5 minutes to 8 hours. Come back, collect, and keep the colony growing.

Expand

Unlock new territory zone by zone, raise silos to store more, and plan a layout that holds.

Train

Barracks turn Regolith into soldiers and tanks. Every unit counts, every loss is real.

Defend

Turrets cover your core. Attackers that ignore them pay in units.

Raid

Pick a target on the world map, deploy your army and watch the fight unfold. Loot what you can carry.

Progress

Experience from every build and harvest unlocks new buildings, bigger storage and tougher opponents.

A world that never sleeps

Rival commanders across the map grow their colonies, train armies and raid on their own clock. Scout them, time your attack, and don't leave your base unguarded.

Rival commanders

Each one runs their frontier differently. Learn their habits — and strike when they look away.
