Post-Apocalyptic Simulator City 20 Takes Players Deep Underground In The Bunker Update

New Bunkers, GPS Navigation System, Dialogue Improvements, and Rebalanced Loot and Enemy Encounters Available Now

April 8, 2026, Milan, Italy – Untold Games has released today the latest update for their post-apocalyptic city simulator City 20. Introducing underground environments, new navigation tools and key mechanical improvements, the Bunker Update takes players to a whole new level of City 20, both figuratively and literally.

Check out the launch trailer for City20’s Bunker Update here.

For the first time, players can now venture beneath the streets of City 20 and explore a vast network of bunkers and underground structures. These fully realised environments are filled with hidden lore, rare items and secrets waiting to be discovered. Designed to offer a darker and more atmospheric experience, the underground delivers a new sense of tension and discovery for those willing to brave the depths.

Supporting the expanded exploration introduced in Version 0.9 comes the GPS, a new gadget that provides players with a minimap directly in their HUD, allowing for smoother navigation and a more immersive exploration experience. By repairing GPS Repeaters, players can connect to local networks, enabling NPC tracking within specific zones, making it easier to locate quest givers, traders and other important characters.

Interacting with these characters has never been better with a full redesign of the Dialogue Wheel. With a new interface that focuses on clarity and ease of use, conversations are streamlined, and removing unnecessary layers of menus means players can stay immersed in the story while navigating interactions more naturally. 

Loot distribution and enemy behaviour have also been rebalanced to reflect the new gameplay dynamics introduced in Version 0.9. While basic supplies remain on the surface, rare and valuable items will now be found mostly underground, rewarding players who take on greater risks. Those risks are enhanced by an expanded Atker threat, who now have an increased presence in underground areas and around Bunkers. They now actively guard high-tier loot, creating a more intense and claustrophobic atmosphere in the dark underground.

The Bunker Update marks a significant step forward in expanding the depth, immersion and challenge of City 20, and offers players new ways to explore, engage and discover secrets hidden beneath the city. 

City 20 is available on PC in Early Access for $19.99. The Bunker Update is available for free to players who own the game on Steam and Epic Game Store starting today.
