Heart of Cydonia

Make sure you’re not on Mars when installing this mod.

Breathe life into one of the Settled Systems’ largest colonies.Cydonia, once a lifeless industrial outpost buried beneath the Martian surface, now begins to awaken.

This mod introduces the first major expansion to Cydonia’s playable area, a new district carved deeper into the colony, with two functional entrances, including a brand-new front gate.

The goal is simple: to transform Cydonia into a living, breathing city, one that reflects its true importance in Starfield's lore as one of humanity’s largest and oldest settlements beyond Earth.

You’ll find: A completely new zone added to the colony Early touches of life: cafés, greenery, and ambient details A layout that blends seamlessly with the original design An atmosphere that feels grounded, functional, and alive This is only the beginning.

The mod will continue to grow over time, with new locations, interiors, NPCs, and activities planned in future updates.
