The zombie apocalypse had to start somewhere. In Quarantine Zone: The Last Check’s new expansion, it started under the Florida sun.
Devolver Digital has released Miami Zero, a large free expansion for Brigada Games’ zombie checkpoint simulator Quarantine Zone: The Last Check, on PC (Steam) and Xbox.
The expansion is set in Miami in the immediate aftermath of the global zombie outbreak. Players meet new survivors on the streets of the sun-drenched resort city and take on a range of new quests and expanded gameplay systems, all with a comedic tone built on Miami’s loud, flashy backdrop and its eccentric cast.
Back to Where It All Began
As the name suggests, Miami Zero is a prequel-style story about the origin of the deadly virus that swallowed the world.
Players are thrown into the chaos of the earliest days of the outbreak, studying the constantly mutating virus and tracing the source of the infection.
A conspiratorial thread drives the story: the deeper players dig, the harder it becomes to believe the government and media line that it was all just an accident.
Unpredictable Miami is also packed with colorful, oddball survivors found nowhere else in the game, and interacting with them adds to the fun.
New Symptoms, Creative Smuggling, and a Yacht Out of Town
Players continue their core job of running the checkpoint while also arranging the one thing everyone in Miami wants: a way out. The key is searching the quarantine zone for a survivor with the technical skills to repair a damaged luxury yacht, the best ticket out of the chaos.
According to the developers and international coverage, the expansion adds a wave of new infection signs tied to the virus’s mutations, including suspicious scars, rotting organs, and intestinal parasites.
A new detailed inspection system also tasks players with finding smuggled drugs that survivors try to sneak in under hats, in clenched fists, or even by swallowing them, demanding sharper and more careful judgment.
Millions of Players and Outreach to Korean Fans
In Quarantine Zone: The Last Check, players run a checkpoint during a zombie outbreak, inspecting a stream of survivors, sending those with suspicious symptoms to isolation or further examination, and directing healthy people to the living zone.
Since its full launch this year, the game has drawn millions of players. Devolver Digital has also been promoting the expansion launch and sale to Korean players through its official Korean X account (@DevolverKR).
Can Miami Zero Address the Base Game’s Weaknesses?
Reception of the base game has been somewhat mixed. On Steam, it holds a “Very Positive” rating according to third-party trackers, but some players have pointed to repetitive gameplay and a lack of polish.
PC Gamer scored it 60, saying it would have benefited from more depth in its core management systems and greater variety in inspection types and patients.
In that context, Miami Zero is notable because it significantly expands the number of symptoms and the inspection mechanics, precisely the areas critics flagged as the base game’s biggest weaknesses.
Who This Is For
Strong fit for: existing Quarantine Zone players, since the expansion is free; fans of Papers, Please-style inspection games who want more variety; players who enjoy dark comedy and conspiracy-tinged zombie stories; Game Pass subscribers.
Cautious fit for: players who bounced off the base game’s repetition; the new symptoms and inspections may help, but it’s too early to judge.
Less ideal for: those looking for zombie action or shooting; this remains a judgment-driven management sim.
What to Watch For
Steam user reviews and critical takes on the expansion itself will be the real test of whether Miami Zero’s new symptoms, smuggling inspections, and yacht escape goal give the loop the depth critics said it lacked. Players wanting the base game at 35% off should note the Steam discount ends today, October 19.
The Takeaway
Miami Zero is a generous free expansion that takes Quarantine Zone back to ground zero, pairing a conspiracy-flavored origin story with exactly the kind of content the base game was criticized for lacking: more symptoms, trickier inspections, and a new goal beyond the checkpoint. For a hit that has already drawn millions of players, it’s a smart move to deepen the formula rather than simply extend it.
Miami Zero: available now, free for base-game owners, on Steam and Xbox (including Game Pass).
