Ecliptica is a first-person open-world colony survival simulator with a fully dynamic economy. Set on a hostile alien planet, you'll found corporations, fight for resources, and build a sustainable future—or be wiped out by ruthless nature, politics, and competition.
Ecliptica
SteamEcliptica is a first-person science fiction sandbox set in an ancient, self-organizing world. You and your colony are alien organisms. After a long flight, the colonists have lost the memory of their origin, retaining only their intelligence and thirst for profit. Now you must take root on a planet that existed long before your arrival and is ready to protect its resources from uninvited guests.

At the core of your colony lies a fair economic model where every survivor is an autonomous market participant.

In Ecliptica, the story is not forced upon the player but grows organically from the state of the world:

The planet holds traces of ancient eras, hidden in the massive and contrasting scenery of your new home:

You are aliens, and the local fauna perceives you as an alien threat:

Thanks to our own game engine based on Qt Quick 3D, Ecliptica supports a fair simulation of thousands of objects and NPCs without performance loss. This allowed us to combine complex physics, deep economics, and large-scale biological expansion into a single seamless experience where you are just one of the forces trying to survive on an ancient planet.
