›Story

A remote colony is established on a hostile alien world through a one-way teleporter. With only a small pool of resources and a handful of autonomous robots, the colonists must explore the planet, secure new sources of energy and minerals, and expand their infrastructure across dangerous terrain.

As the settlement grows, the native ecosystem begins to react. Aggressive plants spread toward power lines and buildings, hostile creatures emerge from the fog, and the planet becomes increasingly dangerous.

The colony’s ultimate objective is to survive long enough to generate the enormous amount of power required to open a permanent tunnel back home while keeping the teleporter and the expanding settlement intact.
