Quarantine Zone is expanding with Miami Zero, a free update that moves the zombie checkpoint simulator to a new setting connected to the outbreak's origins. Check the Xbox Wire for the original details.

The expansion adds 30 characters, additional infection symptoms, contraband to discover, expanded inspection mechanics and a research center for experiments involving infected subjects. New locations include beach and city areas as well as a music festival setting.

Miami Zero also introduces dynamic weather and a larger escape objective built around repairing a yacht. The expansion is free for owners of the base game and is included with the game's Game Pass availability.

Those additions broaden the inspection loop rather than simply placing the same checkpoint in a different backdrop. More symptoms, contraband and research options give players additional information to evaluate while the new characters and locations change what arrives in front of the checkpoint.

The yacht objective also gives Miami Zero a larger goal beyond individual inspections. Repairing an escape route while dealing with weather, infected subjects and the new setting ties the expansion's systems together and gives returning players a reason to revisit the base game's decision-making loop.

Miami Zero adds more than 30 unique survivors with new personalities, voice lines, appearances, animations and body types. The inspection side expands with additional infection symptoms and contraband that can be hidden in several different ways.

The new research center lets players experiment on infected subjects, while a campaign-spanning objective revolves around repairing a ship and escaping. Dynamic weather can shift between sunshine, dust storms and tropical rain across the new Miami locations.

The expansion is available on Xbox Series X|S and PC, including through Xbox and PC Game Pass, and is free for owners of the base game. The original campaign has also received tweaks and updates alongside the new content.

Miami Zero takes the checkpoint simulator back to the early stage of its fictional outbreak, giving familiar inspection decisions a different context. The developer describes more than 30 new survivors with distinct lines and reactions, plus additional symptoms to identify while deciding whom to admit. Contraband detection adds another task beyond recognizing infection: drugs can be concealed under hats, inside hands or in other hiding places, so inspecting a visitor thoroughly is no longer just a question of checking their temperature or appearance.

Brigada Games also outlines a research facility for experiments on infected subjects, a longer quest involving a ship, new areas including a pier and city streets, and variable weather. These elements broaden the activities around the core screening mechanic. According to the Xbox Wire developer post, the Miami Zero expansion is free for existing owners of Quarantine Zone, with availability on Xbox Series X|S and PC. Readers should check the live store for the base-game requirement and local access conditions before downloading.
