Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.

About
“The Mad Virus” has spread throughout the world with the speed of jet planes. The infected are highly aggressive, fast and strong. In a couple of weeks, society collapsed. Cities are empty. There is no electricity, no water, and no food. Yet, there are a few survivors...
Type in the name of the city or town, download the map and start playing! Thanks to OpenStreetMap’s real-world data, you can choose any place in the world for your survivors.
Establish a new “Infection Free Zone” wherever you choose. Set up shelters and production facilities. Adapt existing buildings to new needs. Build new farms and power houses. Establish defenses with walls, gates, and towers.
Utilize your knowledge of the city. What is the best place to defend? Where were the grocery stores, where were the pharmacies? Where would you look for weapons? Remember that it’s dangerous to search the old buildings, there might be some infected lurking in the dark!
Each night, your settlement might be attacked by large hordes of the infected. Fight them off with every tool available - melee and ranged weapons, vehicles, walls and light. Research a vaccine or a cure for ultimate victory, or just enjoy rebuilding entire cities!
Your survivors will surely find other surviving groups. Some will be friendly and willing to trade, but others will be extremely hostile. There might be some fighting involved!

非常优秀的一款即时战略废土重建游戏，前期困难一点，但对于获得的成就感和感悟却是无法比拟的。
After spending about a week or 2 playing this game here is my full review overall 8/10 i think this game has so much potential as an early release game there is so much to do. i really love how you can start off anywhere in the world using maps. the gameplay can be difficult at times but not overwhelming, the different upgrade paths as well as buildings you learn, you can destroy buildings, deconstruct cars for supplies, overall this game is very innovative and i cant wait for what it becomes as a fully released game. (ps) ive never played an early access game with no bugs. i have yet to find a bug in my playthrough

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

this game is great, ive always wanted a game like this but all the games i ever found were either the bare minimum survival or way to advanced, this game is the perfect in between. Not as complicated as project Zomboid but not as easy as a Roblox game, and being able to defend my own house and turn it into a whole community is such a cool factor
Really satisfying to set up your base.
i like the story. that's all!
game bagus namun sayang akan jadi lebih berat setelah mengamankan area pertama
The game is fun and engaging, does have a few issues that pop up here and there, however if your willing to report to the game Devs on discord and or using the bug report tool the issues can be solved. Remember this game is still in a form of beta stage as it is "early Access and still under development" so any player just needs to help out with reports. I deeply enjoy this game
Si.
Hands down one of my favorite base-building games, even in early access the love and care for this game is evident. Patches and updates come out at a very reasonable pace, and the devs listen to their community with so much attention! I've waited a while to write this review because I wanted to get a real feel for this game and it's progress through early access, and I think I've been able to get a great feel for IFZ. Previous game-breaking and annoying bugs I've had to deal with when I first got the game have been dealt with effectively, and are virtually non-existent now. The map is beyond fun to experiment with, I've made upwards to 20 bases and completed the story in about 10 of those. The vast amount of environments and cities you get to try and build in are endlessly fun. One of my favorite saves was a giant base I made in New York's central park! That was before we got Tanks, Mortars, Bunkers, and Explosives update--and I'm super excited to try it again with a harder difficulty! One thing I'd tell new players who are feeling like the game is too difficult or it's learning curve too steep, I'd recommend making a base in neighborhood close to a shopping mall/area, and make the appearance of the undead lower. A mistake I made was making the difficulty too high before I could actually understand the flow of the game, the nightly attacks, when to make use of full moons, taking out large herds of undead, etc. Sometimes it's okay to give yourself a lower difficulty so that you don't rip out hair trying to understand everything. I'm incredibly excited to continue following these devs and their wonderful game, and I certainly cannot wait for more large roadmap updates and QOL updates. Looking forward to the full release!
awesome game i like it alot
