Update (Aug 5, 2026): Quarantine Zombies – Prologue is out now — get it on Steam.
Somewhere north of a dead Chicago, a checkpoint is still standing, and it’s up to one person to keep it that way. Quarantine Zombies – Prologue drops players into that exact nightmare on August 5, and the twist here isn’t another shotgun or another crowd of shambling corpses. It’s the scanner in the hands, and the judgment calls that come with it. This is a zombie game that asks players to think before they shoot, and that small shift changes everything about how the tension builds.
The Setup: A Brother, a Checkpoint, and 30 Days

The premise is simple, but it sits like a stone in the gut. Twenty-eight days ago, a call came in. A checkpoint had fallen, and the person manning it was someone close: a brother, a scientist chasing a cure for the outbreak tearing through the city. Now he’s trapped behind enemy lines, and the only person who can reach him is a cop by background, now serving as the last soldier defending the only checkpoint still holding in northern Chicago. The Army has promised backup in 30 days. Until then, there’s no backup coming. Just a gate, a scanner, and wave after wave of the infected trying to get through.
The prologue only covers the first four days of that countdown. It’s a taste of something bigger, a controlled slice of a much longer fight. But four days is plenty of time to feel the walls closing in, especially once the raids start ramping up and the refugee line never seems to end.
Inspect, Decide, Fight: How the Two Halves Connect

Neither system works without the other. Good decisions at the gate mean better gear for the raids. Surviving the raids means a stronger, better-defended checkpoint. It’s built as one connected pressure cooker, not two separate modes stitched together. The cash and supplies earned from handling that checkpoint well don’t just sit there looking pretty. They loop straight back into base defenses and vehicle repairs, funding the exact tools needed to survive both inside the checkpoint and out in the ruined city beyond it.
There’s a particular stillness to the checkpoint itself, right before the next name gets called. At the checkpoint, refugees show up looking for safety, and it falls on the player to decide who gets it. Full-body scanners and personal inspection tools help sniff out infection, or contraband hiding under someone’s coat. Every person in that line has a story. The game is blunt about one thing: don’t believe any of them right away.
Three choices sit on the table for every refugee. Clear them to leave. Hold them back for a second screening in quarantine. Or eliminate them before they become a problem. None of those calls come free of consequence. Get it wrong, and the infection doesn’t stay outside the gate anymore.
That outward loop is where the shooter side kicks in hard, sending players into infested zones to scavenge and fight through escalating threats like Crawlers, Spitters, Aggressors, and Marine Zombies, and the threat sharpens with every passing day.
The Dual Gameplay Experience in Quarantine Zombies

A ruined Chicago crawling with the undead isn’t new territory, and neither is blasting through waves of them with a shotgun. Most zombie games want fast reflexes and steady aim. This one wants that too, but it also wants a clear head when a scared refugee is standing in front of a scanner with a story that might be a lie.
That tension carries a personal weight for anyone who has played survival games built around trust and suspicion before. Deciding whether to believe a stranger, knowing the wrong call could open the gate to something far worse than a lie, sticks with a player in a way that aiming down a sight rarely does. Add in the hard 30-day countdown, the promised raid waiting at the end of it, and a car that needs constant repair for that final desperate run, and the stakes stretch across two fronts at once. One moral, one physical, both closing in fast.
A word of caution is worth mentioning here. Some third-party coverage vaguely describes the broader project as leaning more action-focused, though how the full release will ultimately balance inspection against combat remains unconfirmed. Anyone hoping for a deep triage-heavy experience should treat this first taste as a starting point, not the finished formula.
When Does Quarantine Zombies – Prologue Come Out?
Quarantine Zombies – Prologue is free-to-play and lands on Steam on August 5, 2026, just days from now. It’s single-player only, with Family Sharing support included, and comes from developer and publisher Stones Games. With no price tag attached and a scope limited to four days of the larger story, it’s an easy way to test the inspect-and-survive loop before any bigger release follows. Anyone craving a zombie apocalypse with a bit of conscience behind the trigger finger should keep an eye on this one.
A scanner and a moral dilemma make for a scarier survival game than another swarm of the undead.

When does Quarantine Zombies – Prologue come out?
Quarantine Zombies – Prologue releases on Steam on August 5, 2026. It’s a free-to-play prologue from developer and publisher Stones Games, covering just the first four days of a much larger planned story about a fallen checkpoint in northern Chicago.
What type of game is Quarantine Zombies – Prologue?
It’s a first-person survival game blending inspection-sim mechanics with zombie action. Players screen refugees at a checkpoint using scanners and inspection tools, then head into infested Chicago to fight escalating waves of infected, earning cash to upgrade weapons and repair their vehicle.
Is Quarantine Zombies – Prologue free?
Yes, it’s completely free-to-play on Steam. The prologue serves as a limited, four-day slice of the full game, letting players test the checkpoint-inspection and zombie-combat loop before deciding whether to follow the larger release when it arrives.
What platforms is Quarantine Zombies – Prologue on?
It’s launching on Steam for PC as a single-player experience. The game includes Family Sharing support, so other accounts on the same device can access it too, but no console versions have been announced alongside the prologue.
Does Quarantine Zombies – Prologue have multiplayer?
No, it’s single-player only. The entire experience, from inspecting refugees at the checkpoint to fighting through zombie-infested Chicago, is built around one player making every judgment call alone, with Family Sharing enabled but no co-op or online modes.
What do you do at the checkpoint in Quarantine Zombies?
Players use a full-body scanner and personal inspection tools to check refugees for infection or hidden contraband. Each person can be cleared to leave, held for a second screening in quarantine, or eliminated, and wrong calls risk letting infection slip past the gate.
What enemies are in Quarantine Zombies – Prologue?
The game features escalating zombie types including Crawlers, Spitters, Aggressors, and Marine Zombies, with threats growing stronger each day. Players fight these enemies during runs outside the checkpoint into infested zones, scavenging supplies while preparing their vehicle for a final desperate raid across Chicago.
