A new Starfield mod significantly expands New Atlantis, adding three districts, additional roads, pedestrian pathways and environmental improvements to the capital of the United Colonies. Created by modder checker90, New Atlantis – A Living Capital entered public beta on November 6, 2026, and is available as a free download through Nexus Mods.
Rather than simply replacing textures or improving existing buildings, the project expands the city’s layout to create additional areas for exploration. The initial release introduces Arcadia, Haven and Vista, three new districts intended to give New Atlantis a more varied appearance and make the settlement feel like a larger, more connected capital.
One of the most practical additions is a network of new roads designed to accommodate Starfield’s REV-8 ground vehicle and other vehicles. These routes provide additional opportunities to drive around the expanded city, while new pedestrian pathways connect different areas and offer more ways to explore on foot.

The mod also changes the environment surrounding New Atlantis. Checker90 has introduced a water purification system that removes the algae previously visible in the city’s lake, giving the water a cleaner appearance. Additional architectural details and environmental decorations have been placed throughout the settlement to make its surroundings feel more developed.
These additions are intended to address the overall scale and connectivity of New Atlantis rather than introduce a separate quest expansion. The project’s emphasis is on reshaping the existing city, improving its appearance and providing more space for players to explore.
The current release remains a work in progress. Checker90 states that the full version is planned after five beta stages, with further additions and improvements expected throughout development. A unique player home is also planned for a future update, although the creator has not provided a release date for that feature.
Performance is another area that still requires work. According to the mod’s description, major optimization has not yet been completed, meaning players could encounter performance problems while exploring the expanded city. Checker90 plans significant optimization improvements in future updates and has specifically requested feedback from console players to help assess performance across platforms.
Compatibility is also limited when using other substantial New Atlantis modifications. The creator confirms that New Atlantis – A Living Capital is incompatible with New Atlantis Awaits and other mods that make major changes to the same city. Players already using extensive city overhauls should therefore review their load orders before installing the expansion.
The mod’s Nexus Mods listing shows that the original beta was uploaded on November 6, followed by an update to beta v1.5 on November 8. The project is also listed on Starfield Unity for PC, Xbox and PlayStation, giving console players access to the expansion through supported mod distribution channels.
Although the beta is currently free, checker90 intends to submit the completed project as a paid, achievement-friendly Creation once development is finished. No final release date or pricing has been announced.
For now, the free beta allows Starfield players to explore the three new districts and expanded transportation routes while development continues. Players interested in the environmental overhaul should account for its unfinished optimization and compatibility restrictions before adding it to an existing modded playthrough.
