Quarantine Zone: The Last Check's Free Miami Zero DLC Sends Players Back to Ground Zero

Brigada Games has sent its runaway hit Quarantine Zone: The Last Check back to where the outbreak began. Miami Zero, a free content update revealed and released on October 15, drops players at the original checkpoint on Florida's coast, months before the game's familiar northern outpost existed. The studio, working with publisher Devolver Digital, calls it the biggest update the "zombie checkpoint simulator" has received since launching in January.

Back to ground zero

The base game cast players as an overworked border officer screening refugees for infection with X-ray scanners, questionnaires and a healthy dose of paranoia. Miami Zero rewinds that premise to the first days of the crisis, when the virus was still an unconfirmed rumor and the checkpoint was a makeshift pier operation rather than a fortified outpost. Game director Egor Zaitsev wrote in the official Xbox Wire announcement that the team wanted the expansion to feel like "much more than just a change of scenery," rebuilding the inspection loop around a city instead of a border crossing.

What the free update adds

• A new campaign and storyline set in early-outbreak Miami, with its own cast of over 30 survivors, each with distinct voice lines and appearances
• New symptoms to spot during screenings, including suspicious scars, rotten organs and stomach parasites
• Drug and contraband detection, with suspects hiding items under hats, in their cheeks or swallowed outright
• A dedicated research center for experimenting on captured infected subjects
• New locations, including a public pier, downtown streets and a beachside music festival
• A dynamic weather system cycling between sunshine, dust storms and tropical downpours
• Upgraded environmental audio across the pier, streets and festival grounds

Sharks, drones and a getaway yacht

Where the base game kept its tone grim and procedural, Miami Zero leans into the setting's absurdity. Officers can pilot a drone to scout the checkpoint line from above, and the Xbox Store listing confirms suspects judged too dangerous to process can be fed to the sharks patrolling the marina rather than detained conventionally. Zaitsev described the team letting its "imagination run wild" on the expansion's new minigames, and admitted some of the resulting content is "a little wild 'n' wacky" compared to the main campaign's bureaucratic dread.

The throughline connecting the gruesome inspections to the new systems is the player's long-term goal: repairing a damaged luxury yacht moored at the marina and recruiting enough able-bodied survivors to crew it out of the quarantine zone before the city falls.

Free for every owner, available now

Miami Zero carries no separate price tag. Anyone who owns Quarantine Zone: The Last Check on PC or Xbox Series X|S gets the expansion automatically, including players accessing the game through PC Game Pass and Xbox Game Pass. The base game, now discounted to $12.99 on Steam from its $19.99 list price, originally launched on PC on January 12 before Devolver Digital brought it to Xbox Series X|S and Game Pass later in the year.

A surprise hit gets its biggest test yet

Quarantine Zone: The Last Check built its audience the way few checkpoint-inspection games do: through viral TikTok and Twitch clips of players agonizing over morally grim calls at the border gate, each clip framing a tiny bureaucratic decision as a life-or-death gamble. That attention translated into real sales, with the game crossing a million Steam wishlists before launch and prompting Devolver Digital to sign on as publisher ahead of its console debut. Miami Zero is the clearest signal yet that Brigada Games intends to keep building on that momentum rather than treat the January launch as the finish line, and its free price tag suggests the studio is betting on word of mouth over a paid expansion to pull lapsed players back in. Zaitsev closed the Xbox Wire post by urging both lapsed players and newcomers to give the checkpoint another look now that Miami Zero is live, signing off with a reminder to pack sunscreen for the trip south.
