Back to Miami, where the infection began
Quarantine Zone: The Last Check has a new reason to reopen its checkpoint. Miami Zero, a free expansion detailed by Brigada Games on October 15, is available now on Xbox Series X|S and PC, including through Xbox and PC Game Pass. The new campaign returns to the early days of the outbreak, moving the screening operation to Miami as the infection begins to spread.
More people, more things to investigate
The expansion adds more than 30 unique survivors, alongside new inspection mechanics, equipment and symptoms. Contraband searches also become more involved, with drugs hidden in clothing, swallowed or concealed in other ways. The basic decision remains whether to admit, quarantine or reject the people at your checkpoint, but the update gives players more evidence to examine before making those calls.
Research, repairs and changing weather
Miami Zero introduces a research center for experiments on infected people and a campaign-spanning effort to repair a ship and escape. Dynamic weather brings tropical rain and dust storms, while new surroundings include a pier, city streets and a music festival. Brigada also says the original campaign has received improvements, giving returning players changes beyond the new setting itself.
How the expansion fits the original game
Miami Zero is free for owners of Quarantine Zone: The Last Check. The Xbox Store now describes the Miami content as a free update and confirms support for PC and Xbox Series X|S, as well as Xbox Play Anywhere. The broader game still combines survivor screening with resource management and checkpoint defense. For existing players, the update builds on those responsibilities with a new origin-story campaign rather than requiring a separate expansion purchase.
