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...

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 2,419 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.

тупая ♥♥♥♥♥ без нормальных обнов
This is a solid game, and surprisingly complex. There's a learning curve for sure, and it can be off-putting for new players. I actually stopped playing after less than 30 minutes and didn't touch it again for months out of frustration. I'm glad I gave it another go, however. First off, you need to take bite-sized pieces out of the progression. When you're starting off, your gear is mediocre at best, ammo and healing supplies are scarce, and you're probably going to die more than you succeed. Once you loot or buy some better gear, build some base modules, and get into a groove with encounters, you can move across the map more confidently. You should absolutely prioritize upgrading your storage above all else - I found it's basically impossible to start doing real work until you've got at least Storage 2. I've found it helps to keep a small mindset when approaching your hunts even after you are established - you will collect a couple of things you need, maybe accomplish a subtask, and gather a small amount of supplies and resources. Even at a slower pace, I've found the character and base progression to be rewarding. The combat is challenging but approachable. You need to be accurate with your cursor to avoid misses and glancing shots. There's no cover system, so you need to be strategic about using corners and features in your surroundings. The game rewards stealth/ambush tactics against human enemies and I've had my most success with long range weapons. Faster enemies are best handled with close range weapons (I was getting housed by wolves and ghouls until I realized I could kill them more easily with a pistol than a rifle). There's probably a play style that supports faster-paced run-and-gun action, especially once you get better gear, but I haven't worked it out yet. This hasn't hindered my enjoyment though. The graphics are as advertised. They work, and there's been a lot of attention paid to little details in the weapon customization, but it's very much a pixel shooter with a nostalgic early-to-mid 90s feel and that comes with its own set of challenges. I have trouble finding bodies in terrain features if I lose track of where an enemy went down. I also wish the audio localization was a little more precise, as you can hear footsteps and mutant sounds, but the direction they came from doesn't always line up with where you find them. These gripes aren't enough to ruin the experience for me, however. I generally like to wait until I've finished a game to write a review, and I'm only about half way through at this point (I've beaten a few bosses and unlocked half of the areas). I'm breaking from that because I noticed that this is currently sitting at "Mixed" and I wanted to add my opinion. I'm having a lot of fun with Zero Sievert. It's like a single-player SNES action game with RPG elements that's inspired by STALKER and Escape From Tarkov. If that appeals to you in any way, then you'll probably enjoy it.

Enfin en français , avec Nexus mod :)
I love it!
2026-7-12 有个 BUG 就是我在绿军的将军那里做了一个任务要杀死第一张地图的伊格尔,我已经杀死他并上交任务成功了,但地图上标示伊格尔的房子的位置的黄色图标并没有消失且依然村在。 还有一个问题,就是你这个游戏里有一个技能点,只要玩家选择了技能点就能在地图上增加一个撤离点。但我用过以后才发现,新增的一个技能点与原有的技能点距离太近了,我以为说是一张地图左边有了撤离点则新增一个在右边这样。所以你这个技能点需要优化啊,否则我点出来有什么意义? 从酒保那里得到的任务叫‘化学活动’,这个任务的介绍文本依然是英文,尚未翻译成中文。
It's fun, at times challenging and a lot of organizing if you are a hoarder like myself :)
Look I love this game but it doesn't run on my hardware suddenly when it used to run perfectly. Now that could just be me being broke but it breaks my heart either way. Maybe they made optimization changes but I'm not sure
This game is a piece of ♥♥♥♥. The control is poor garbage. And it is definitely not optimized for the steam deck. There much better games than this. Don't buy
Otro juego para demostrar que los triple A no son necesarios
If you like the Tarkov experience without the sweats, with that classic game feel, this is for you.
