FREE Zombie Expansion Just Dropped — Quarantine Zone Takes You to Miami (And It’s Pure Chaos)

Your shift at the checkpoint is not over. In fact, it is just getting sunnier, stranger, and a lot more chaotic.

Quarantine Zone: The Last Check from Brigada Games and Devolver Digital has received a brand-new expansion called Miami Zero, and it is available now on PC and Xbox. The best part? It is completely free to all owners of the original game, and it is included via Xbox and PC Game Pass. If you have been waiting for a reason to put the gloves back on and step up to the checkpoint, this is it.

Miami Zero takes the zombie checkpoint simulator to sunny Florida, to the very beginning of the outbreak. Instead of dealing with the aftermath, you get to live through the first chaotic days, when no one quite knows what is happening, the infection is still changing, and the city around you is falling apart in real time.

Welcome to Miami, where it all began

Miami is bright, loud, colorful, and wildly unpredictable, and that contrast is what makes Miami Zero so effective. The original game built tension in a grim, cold checkpoint. Miami flips that on its head. The sun is out, the streets are soaked with rain one minute and blazing with light the next, and the survivors you meet are as eccentric as the city itself.

You step into the first days of the outbreak and start to discover how the infection that would soon engulf the world actually began. The city is full of characters you will not find anywhere else, people with their own stories, quirks, and reasons for being at your checkpoint. Some are desperate. Some are suspicious. Some are just trying to survive another day in a city that is coming apart.

That setting gives Miami Zero a different energy. It is still a tense, high-stakes checkpoint game, but the Miami backdrop makes every shift feel fresh. You are not just repeating the same routine in a new map. You are experiencing the origin of the outbreak, in a place that feels alive even as it falls apart.

The core job is still the checkpoint

For anyone who has not played Quarantine Zone yet, here is the pitch: you are the last line of defense at a checkpoint, deciding who gets through and who does not. You inspect survivors, look for symptoms of infection, use tools to test and verify, and make judgment calls that can save lives or doom them. Let the wrong person through and the infection spreads. Turn away the wrong person and you may have condemned someone innocent.

That tension is the heart of the game. It is part inspection puzzle, part moral dilemma, part time-management scramble. You have to be careful, but you also have to be fast, because the line keeps moving and the pressure keeps building. Miami Zero keeps that core intact while adding new layers on top of it.

The original game found a huge audience this year, with millions of players stepping up to protect humanity from the outbreak. Miami Zero builds on that success by giving returning players a new city, new systems, and new reasons to care, while giving new players a perfect entry point.

An infection that keeps changing

One of the biggest hooks of Miami Zero is that the virus itself is still evolving. You are not just dealing with the same symptoms you already know. You have to study mutations, learn new signs, and trace the infection back to its source while the situation around you grows stranger by the day.

The deeper you dig, the harder it becomes to believe the outbreak was simply an accident. Miami Zero leans into that mystery, adding an investigation thread that runs alongside the checkpoint work. You are not just screening survivors. You are trying to understand what is really happening, and why.

That gives the expansion a stronger story drive than a simple new map would. Every shift teaches you a little more. Every new symptom or tool changes how you approach the next survivor. And every clue makes you want to keep going to find out what is behind it all.

New symptoms, new tools, new challenges

Miami Zero adds new gameplay, new survivors, and new quests, along with new symptoms, new tools, and new challenges to keep you guessing. That is important, because the checkpoint formula lives or dies on variety. If every survivor looked the same and every symptom was obvious, the game would get stale fast. Miami Zero avoids that by constantly introducing new wrinkles.

New symptoms mean you cannot just rely on what you learned in the base game. You have to pay attention, learn the new tells, and adapt your inspection routine. New tools give you new ways to verify what you are seeing, but they also add new decisions: which tool to use, when to use it, and how much time you can afford to spend on one survivor while others wait.

New quests and new survivors keep the world feeling alive. You are not just processing a faceless line. You are meeting people with needs, stories, and problems, and your choices affect how their stories play out. That human element is what lifts Quarantine Zone above a simple simulation and makes it memorable.

Rebuild your way out

Miami Zero also adds a bigger goal beyond the checkpoint itself. While you keep the checkpoint running, you work toward the one thing everyone in Miami desperately needs: a way out. You find survivors who can help restore a damaged luxury yacht and turn it into your best chance of escaping the city.

That yacht project gives the expansion a clear long-term objective. Every shift is not just about surviving the day. It is about building toward escape, gathering the right people, and making the repairs that will get you out of Miami before it is too late. It adds a satisfying sense of progress to a game that can otherwise feel like an endless grind.

It also fits the Miami setting perfectly. A luxury yacht is exactly the kind of escape plan a city like Miami would produce: glamorous, impractical, and somehow the best option you have. Fixing it up while the world falls apart around you is a great metaphor for the whole expansion.

Free for owners, on Game Pass, and the base game is on sale

Miami Zero is available now on Xbox and PC, including via Xbox and PC Game Pass, and it is free to all owners of Quarantine Zone: The Last Check. If you already own the game, you can jump into Miami Zero without paying anything extra. If you play through Game Pass, you can play it as part of your subscription.

To celebrate the launch, the base game is also 35% off on Steam from October 15 to 19. That makes this the best time to start if you are new. You can pick up the base game at a discount, play through the original checkpoint experience, and then head straight to Miami for the expansion, all in the same week.

Whether you are a veteran who has already pulled dozens of shifts or a newbie who has never inspected a single survivor, there has never been a better time to step up to the checkpoint. Miami is waiting, the infection is changing, and the yacht is not going to fix itself.
