Infection Free Zone: a refuge on a real-world map
Infection Free Zone is a post-apocalyptic survival and city-building strategy from the Polish studio Jutsu Games (published by Games Operators). Its standout trick, which almost no other game has: the map is generated from real-world satellite data. You can set up your base in Paris, London, your own hometown — or literally any spot on the planet — and defend streets you actually know.
The story kicks off in April 2030, after the “Mad Virus” turned most of humanity into aggressive infected. You're left with a handful of survivors and the ruins of a familiar world, and from that you have to build an enclave that lives to see the morning.
How day and night play out
The whole loop runs on a day-night cycle, and it's not cosmetic — it's two different games inside one. By day you send squads of armed survivors to comb buildings for food, materials, fuel and weapons. You repurpose existing houses into med bays, workshops, farms and research centers — the city is already built, your job is to rethink it. At night the infected come, and anything you haven't reinforced with walls, gates and watchtowers is suddenly exposed.
What this product includes
You're buying the full current build of Infection Free Zone and receiving it as a Steam gift, straight into your library. This is the base game — the real-world map generation, survivor management, base defense and the vaccine research tree. No trimmed-down demo: a complete copy lands on your account and keeps updating automatically.
Early Access — straight talk on the status
Infection Free Zone launched into Steam Early Access on 11 April 2024 and, as of 2026, is still being developed: the studio keeps adding mechanics, content and balance fixes. For you that means the game is already fully playable, yet still growing — every patch arrives on your account at no extra cost. If you enjoy jumping into a project while it's actively evolving and watching it change update to update, this is your kind of game.
Who it's for
For players who sink into city-building and resource management but want the tension of survival and real stakes: misjudge your defenses and you lose people. If you're into zombie city-builders like They Are Billions or the harsh colony management of Frostpunk, Infection Free Zone sits on the same shelf. And if you prefer a more intimate, personal kind of survival among the infected, take a look at Project Zomboid too.
Depth that keeps you hooked
Behind the simple premise of “scavenge by day, fight by night” hides real strategic depth. Survivors aren't faceless units: they need food, shelter and morale, and sagging morale drags down the efficiency of your whole enclave. In parallel you push a research tree — from basic upgrades all the way to developing a vaccine, which in this world is your long-term goal. Other survivor groups are scattered across the map: some you can trade and negotiate with, others you can't. And vehicles you find and repair turn your expeditions into far bolder, longer-range raids. It all adds up to a loop that's hard to step out of: “just one more night, then I'll sleep.”
What to know before buying
This product is specifically the base Infection Free Zone game, without extra content like the Supporter Pack (cosmetic vehicle skins, decor, soundtrack and wallpapers are sold separately and aren't included here). The base version is entirely enough to get the whole game: real-world map generation, survivors, defense and research. It's lightweight in the spirit of indie strategy titles and runs on Windows; before buying, just make sure your Steam account region matches the gift region.
How we deliver the gift
Delivery goes through Steam Gift. In the order you provide your friend invite link and your Steam account region. Our bot adds itself to your friends, sends the gift (usually within a couple of minutes) and automatically leaves your friends list once it's delivered — you don't accept anything manually, and Steam Guard isn't required. Two conditions Steam needs to accept the gift: your account region must match the gift region, and Infection Free Zone must not already be in your library.
Common hiccups
If the bot couldn't add you, it's almost always because friend requests are disabled in your profile settings or the invite link has expired. Allow friend requests, refresh the link and message us — we'll finish the delivery. And double-check your account region in advance: a region mismatch and already owning the game are the two main reasons Steam refuses a gift.
