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 · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 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.

除非你的反应速度和苍蝇一样快,否则你别想在这个游戏里活过一秒
Not for me. I tried it years ago and couldn't get into it either, thought maybe all the free updates would change my experience but it did not. The game has definitely improved alot though, but I'll list my personal gripes in the hopes they can use that to further refine the experience. Issues I had: - My number 1 issue was not being able to fast forward time in any way without the first bed upgrade. I wasn't lucky enough to find the right parts for the bed before the first night rolled through. And I've died like 10 times in a row trying to survive a night raid, and it resets me back to before the raid. So I'm stuck in an infinite loop of doing night raids that I can't complete because even with the headlamp it's extremely brutal to see anything before it gets close enough to kill you. Please for the love of god devs put the level 1 bed in the hideout by default. - The game is extremely grindy (which is good in moderation) but I think it's a bit much personally especially with the stash space. You run out of stash space in literally the first or second raid if you get a good enough haul. They need to add more stacking at least so you can stack things alot more or stack things you couldnt stack before ONLY in the stash. - They need to make it easier to tell when NPCs are friendly and when they are not from a distance. It's insane how many times I swear those were hunter NPCs just for me to get close and have them all mag dump my face without warning. - Idk if this is just because the backpacks get alot better later but backpack economy feels horrible, I feel like I reach max encumbrance within seconds of starting a raid. I have a few backpack upgrades too I'm not just using the starting bag. I was really disappointed when I saw there was no setting in the big custom difficulty system for altering the backpack weight capacity. I really hope they add that because some of us don't like being restricted so hard with weight limit when your grid inventory is ALREADY limited.

Inventory management and UI is awful. I don't have the greatest eyesight so this might be on me, but being able to tell enemies apart from the background and terrain is really difficult, even in full daylight. Enemies don't have the same problem so this feels unfair to me. Escape from Duckov is a way better version of this game, has way higher usability, inventory is better, stash and base are easier to upgrade and make more sense. Just way better. It hasn't been even 2 years yet and the sequel is already being developed. Feels like they maybe could have spent that effort making this game feel better.
I guess its just not for me.
하면 할수록 재밌있음. 처음에 '몹들이 왜이리 쎄?'하는데, 파밍하고 좋은 무기 구하면 강해지고 재미있었짐. 나처럼 똥손인 애들은 난이도 쉬울 걸로 하면 재미있을니까 자존심때문에 보통난이도로 해서 포기하지말고 이지난이도로 하자!!
The game runs like crap. Its weird that its made to look like an old school game, but its only playable on newer gaming rigs. I have a decent PC, went thru all the online trouble shooting i could find for the game, but it runs like crap. i can easily play games like balders gate 3 with no issue on highest settings, but this game chugs along at an unplayable pace at lowest settings. i had it to long and my chance for refund has expired, so just a heads up...dont get it unless you got a very modern and decent PC. go with escape from tarkov instead. That is also a game my PC runs just fine too....so no idea why it struggles on this one.
I remember having fun with this. why the hell is it taking 90% of my GPU? what???
What's the point of armor and recoil when the enemy can care less about it?
О вреде гордыни и чувства нескромного превосходства. Половина сюжета пройдена. Внимательно, осторожно, с умеренными рисками тщательным контролем всего и вся. Гг почти развит до максимума, он силён, сыт, но не ссыт, красив и умён. Дотошен, прозорлив, уделяет время Брюкве и не чужд прекрасному. Хорошо владеет тремя видами оружия и неплохо ещё двумя. А в планах стать гуру всего стреляющего и взрывающего. Обзавёлся прекрасными умениями для выживания в этом нелёгком мире и отращивания стальных бубенцов. А также отлично экипирован самыми современными видами орудия убийства себе подобных. При себе и в сундуке "великой жадности" у него половина склада печенек и тортов. Он готов ко всему. Даже попытаться проткнуть в спину Злого Санту трёхзубой вилкой, если таковая попадётся ему в его странствиях. Но находятся только четырёхзубые, что явная дискриминация по отношению к трёхзубым вилкам. Но гг не готов к необузданному коварству внезапных моментов. Внезапно может случиться понос, выброс, когда гг находится в чистом поле с тяжёлым рюкзаком всякой подобранной Брюквы. Внезапно ослепнуть от вспышки. Внезапно наступить на собственную мину, благополучно позабытую. Внезапно нанизаным на бивни кобанчика, увлечённо роящегося в останках очередного неудачника за камнем. И самое коварное, внезапно встретить главнюка в считанных сантиметрах от своей многострадальной жжжжж.... в тот момент, когда гг ставит мину, бухает водку, пьёт кока-колу или предаётся разврату... 😵
Extremely addictive and the loot shooting fun is so enthralling even if its not a third person or first person game. It will deliver what you are looking for in single plyer loot shooter
