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.
Reviews, worldwide (the counter carries no country): 3.57/day in the week to Aug 14 → 20.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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.
About
Half a million players have stepped into the radioactive ruins, scavenged for precious loot, and fought tooth and nail to make it out alive. That number represents not just sales, but stories. Thousands of extraction runs, loadouts tested, factions faced, and unforgettable moments of survival and chaos.
For those who are making runs into the radioactive wasteland, THANK YOU! And for those of you thinking if you should join them, well, I know 600,000 reasons why you should...
Happy hunting...
The world has ended. ZERO Sievert charges you with scavenging equipment across multiple areas, all set in an atmospheric fictitious post-apocalyptic Eastern Europe setting. Your base of operations, the bunker, is filled with traders, modding stations, and areas to make your own, providing you with progression across your excursions into the wild.
Once you’re out in the wilds of the wasteland, however, the situation becomes a lot less secure. Across the six biomes of the game, you’ll initially be armed with little more than a gun and a bottle of water, after which point it’s up to you to recover items, take out bandits, and most importantly, get back alive.
And be warned; the nuclear fallout may have impacted some of the local wildlife…
With a complete new hunter experience, our tutorial takes you (loosely) by the hand and equips you with the knowledge, skills and guns you'll need to to survive and thrive in the world of ZERO Sievert.
Procedurally generated maps make every journey different, with ever-changing hiding spots, loot locations, weather, and layouts. With six maps to explore, be sure to adapt and learn each one's secrets to get in, get out, and get better.
Hunt in a way that suits your playstyle, with over 50 unique guns and 150 mods that can be combined to make you the biggest threat in the wastes of ZERO Sievert. Create a weapon that suits your style or focus on stats to become the ultimate hunter.
As you survive the harsh wasteland you’ll gain experience, sharpening your skills and unlocking new ways to become a deadly hunter. The Weapon Skill System allows you to level up various weapon types, boosting stats such as reload speed, damage, movement speed, and even unlocking unique perks tailored to each weapon. Beyond weapon XP, you can level-up your hunter with unique perks to help navigate the wasteland, tackle tough challenges, and take on more enemies.
In Zakov you’ll encounter The Green Army, a group dedicated to maintaining law and order, or the Crimson Corporation, a global pharmaceutical and technology giant. As a hunter you can choose a faction, earn reputation, unlock unique faction quests, and collect special, high-tier loot to aid you in your journey throughout the wasteland!
Multiple questlines guide you through the world of ZERO Sievert. Through talking with a range of characters you’ll slowly unravel information and lore about the world that’s been left behind. Alongside this, there are more than 100 different items to loot which can be used to craft new items, upgrade your own base, and trade.
The Steam Workshop offers all new ways for you to experience the post-apocalyptic world of Zakov. Dive into a wide range of game changing mods that introduce new weapons to your arsenal, factions for you to work for, NPC’s to discover, quests, languages, and much more.

I'd like to review this game positively. It seems like fun, but the optimization is just horrendous. I've got a pretty beefy gaming laptop, and I could only get the tiny tutorial map to run smoothly by playing in windowed mode with all specs lowered to the floor. Even then, I encountered repeated crashes every 2-3 minutes. Found out some people solved this problem by manually changing the GPU the program is running on since it was using my integrated GPU rather than my gaming one. Indeed, after doing so I never encountered another crash for the next 30ish minutes I played the game, but upon loading into the first real level, my frames again dropped to below a playable level and I had to get a refund. If the game looks interesting to you, I'd say buy it and see if the game is stable on your system because it looks like a great 2D extraction shooter, but be prepared to refund if you can't get it to run.

Avant tout sachez que la note "plutot positive" est uniquement dû au passage à la 1.0 et l'annonce de zero sievert 2 ( qui fait que les gens ont peur que le jeu soit abandonné, ce qui n'est pas le cas du tout au vu de la maj qu'ils viennent de sortir). Le jeu est incroyable, le parfait mélange entre stalker et tarkov, en ayant de multiples options de difficultés changeable à tout moment (perdre TOUT son equipement à chaque mort, perdre uniquement ce qui est ramassé durant le raid, etc etc) ce qui peut le rendre casu friendly, mais aussi fait pour les tryharder. Bref j'ADORE ce jeu. J'y ai foutu 17h en quelques jours lol. merci pour les travaux.
Boars are too dangerous, anomaly's just suck and more or less instant kill. But the most un-fun feature has to be the hideout building, the resource requirements for even a basic bit of furniture is absolutely ridiculous and beyond grind.. Levels are locked behind progressing tasks, so you'll be seeing an awful lot of "The Forest" To the Devs: Don't bother with some generic response about lowering difficulty or the game can be "punishing" It's more the game is just badly balanced. I'm a GAMMA Invictus player and completed games with hardcore / ironman mode in this genre many times. It's just not a good game, honestly..
Its a fun cycle of loot stuff and upgrade base then go out with better gear to loot more stuff
Despite the game's system requirements being described as being able to run on anything that is "Everything that's not 7+ years old," The game has several optimization issues. It seems that its been this way for years as well, as I've seen posts and people in their community server complaining about just this for up to 2 years? If your game doesn't run on old hardware (in some cases even new hardware), don't market it as a game that runs on literally anything.
One of the reviews I will come back to, for now - it's been a great first impression. I'm pretty certain this game already deserves a positive review for a few things: 1. Combat. The core gameplay loop revolves around entering a map, doing whatever you feel like doing with events, quests, somewhat randomly generated content, and trying to extract. During which, you will encounter many different enemies, many different guns will point at you and you will deal with many of them differently. There's different tactics between enemies, and it doesn't feel super unfair. For those people looking for the most extreme, definitely choosing to lose items on death is a great option, but this game doesn't require you to do it. 2. Sound. It's.. surprisingly good. Except for a few random places cutting off the ambient sounds, firefights sound great. Enemy footsteps usually help you assume where and if there are enemies - it helps, especially at nights, when visibility is incredibly limited and enemies use their flashlight mostly temporarily, when looking for you in the vicinity they hear you walk/shoot etc. 3. Loot (Content). I played a few attempts on one map only, and there is quite a lot of items you can pick up, carry over and use for either crafting, or selling. Apart from that, keys and keycards to access locked places, nice medicine system, stimulants, ammunition - and so on, and so on. 4. Mods. The game supports mods. While I haven't tested them yet, I definitely will if there is some good content. It feels like a game that can grow extremely well with some nice mods. Absolutely great modding platform. (Remember, this is mostly first impression review, I will probably return to it at a later time).
鸭科夫一出来直接就对比成一坨了,这东西很多年前就没怎么更新了
ただの死にゲー 時間の無駄
Could have been good. Inventory mgmnt is like getting kicked in the ♥♥♥♥ repeatedly. Game was abandoned so the Dev can make a sequel without finishing the original. GG
是我的错觉吗,怎么感觉比起测试的时候删掉了好多任务,现在任务线好短
