Now with over 600,000 copies sold, ZERO Sievert is a tense top-down extraction shooter that challenges you to scavenge a procedurally-generated wasteland, loot gear, and explore what’s left of a devastated world. When the odds are stacked against you, you’ll need to do more than just survive...

Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
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 · Poland over the last 30 days: the 21 chart moves that followed a price cut of more than 20% went a median of 12 places towards #1, and the 2,501 moves with no price cut behind them went 1 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.

In short, this is a really addicting and fun game. I can definitely recommend it. It is like a mix of Stalker and Escape from Tarkov, so the game has gotten a lot of influence from both of these. It is very good, and don’t let the pixel graphics fool you—it is very engaging and fun. The game is also very unforgiving, and in the end, you can make it as hard as you want. The best part for me is that this is fully single-player, which means I can enjoy it however I like. The game also has mod support, which is really important in my book. There are some bad things as well: Daily missions are dynamically placed, and since the map changes every time you go there, this can lead to mission objectives being inside a mountain or otherwise in an inaccessible area. Some traders can end up in a similar way. For someone red-green colorblind like me, it is really hard to recognize who is who. Sometimes it is even hard to distinguish crimson guys from others. I wish there was an option or a change in the game to add more contrast to the clothes of different factions. The game also doesn’t tell you much about how to play it.

game is good
Entertaining game
Tout à fait excellent !
muy bueno la verdad.
Un juego de extracción de disparos 2D impecable, tiene mecánicas variadas, puedes pasarte horas haciendo misiones de las cuales mueres 5 de cada 6 partidas, si no tienes internet, lo recomiendo, más aun si eres de los que les gusta los juegos retro! Aunque lo pongas en fácil, la dificultad sigue siendo alta y exigente!
先說優點,很真實,不管是換武器的時間、武器攻擊方式(自動、半自動)、彈藥的分類(幾毫米都給你寫的明明白白),子彈亂飄的真實性,對於玩家來說都很有挑戰性。 但說實話有點太難,出去探索五次只有一次成功活著回來,除了前面的指引外,感覺一開場就是死亡難度,護甲跟沒有一樣,亂七八糟的製作系統玩了兩個小時竟然一個倉庫都做不出來....
need more gun, map, faction. NEED MORE
Edit#2: I've gone back and forth on this game a number of times. I still maintain this is a good game and the gunplay is as good as any game out there. I'm currently back enjoying the game but can't escape the fact that very little has changed in the game since I first played it last year. However the game loop is very quick and enjoyable - a prime example of "one more go" and "how is it 2am?!". Edit#1: I can't recommend this game unless on offer. It'll give you a few good hours and the gunplay is really on point for both sound and feel. However nothing really new gets added to the game and not being available on GeForce Now feels like a huge mistake.
great game when this ♥♥♥♥ not bugging fix your ♥♥♥♥♥♥♥ server
