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 · 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.

这确实是个好玩的游戏,但是我在游玩中却遇到过很多带来负面感受的事 1.睡眠的压力和建设家园的机制使我不得不放弃我的第一个档,事实上直到第二个档后期我才知道雇佣兵床是可以临时用来睡眠 2.应增加保险机制,可以放在技能位中,但不能没有,尤其是剪线钳等工具难以获取和带出,使得我在失去时挫败感更强 3.击杀后尸体难以找到,虽然有乌鸦作为指引,但是地图中大量的场景物品会遮掩尸体的存在 4.卢布的存放上限应该提升,而非999 5.在我手动调整后能够存放的物品却在自动整理时因为奇怪的整理方式导致物品直接消失,这十分难受 6.在低难度时可以引入声纹系统,大致标明敌人的方位等,撞脸时ttk会非常快 7.地图是否有动态难度调整,入场价值和护甲等级变高后感觉敌人的装备也相应变好了,亦或是随任务推进而增加
Game broke on proton, doesn't take in input to get past the first screen. After messing around I got to launch it once but when quitting to figure out if I could reproduce the solution (I couldn't), I got hit with a 'hit exit twice to exit and lmao here's an add for Zero Sievert 2 please wishlist' I find advertisements of any kind to be grating and the fact that I can't play the game after the latest update ONLY TO BE SHOWN AN AD is grinding my gears. Buggy game, not recommended even if it's fun, wait for a lot more bugfixes ig

MODまで手を出して気が付いたら700時間プレイした。難易度は最初でも選べるし敵の強さは途中でも調整できる。武器バランスが気になるなら自己責任だけどGAMEDATAからweapon等をメモで開いての調整も手軽。雰囲気もいい。最初から全て敵でプレイヤーのみを狙うとかがないのも良い点(例外勢力あり)。中立勢力はこちらから危害を加えない限り基本敵対せずちゃんと強い。案山子じゃない。ありそうなもんだが人間用の近接武器はない存在しない。 他の人のMODも参考に武器等の差し替えも簡単。だが新たに追加して敵にも装備させるとなるとjsonの編集はテキストの編集だとダメでVSCodeUserの様な別途ソフトが必要。さらに画像の読み込みにはmodscriptが必要(本体のweponjsonで既存武器をコピーして名前を変え新武器ステータスを組んでて、他の人のMODscriptに相乗りする形で画像差し替え、これで楽してすまん)。似た様なゲームはちょいちょいあるから人によってはコンテンツの少なさに不満を持つかもしれないがこの値段なら十分。インディーズゲームはPS1の時代で中古売り場から良ゲーを探すのに似ている。なので比較はアゴのシャアが出て来る実写ガンダムのゲームとかになる。あっちは500円だったが比べてみよう。
理论上想给好评,但是希望作者不仅是回复给了差评的人,这样对支持你的或者给你认真留言的人很不礼貌,伤害了认真留言玩家的心情,我看到很多很高质量的评论没有得到开发者的感谢,但是只要是差评就会被认真回复,希望作者注意这一点
不知道为什么,版本更新后操作越来越卡,换电脑后操作还是有一种奇怪的滑腻感,就是游戏本身还是好玩的,但是优化给人体感很差。
傻逼游戏撤不出去,那狼猪数值给那么高,策划福瑞空
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
If you have multiple monitors: make sure you play the game right after purchasing it to see if you need a refund. Unfortunately, I've requested a refund because I wasn't able to control my cursor in game. It looks like this is a known issue related to your monitor, particularly if you have multiple displays and play games on anything other than your default display. The in-game Video settings/options were also limited and didn't help my issue. I don't want to change my PC monitor settings for just this one application, so I'll have to pass. :-(
很好玩的游戏但内容有点少但加了MOD之后还好,而且希望二代出联机版,一个人玩的话有点无聊
if there was a mobile version of this game i might become addicted again sure, the game is not perfect, still got some bugs and glitches here and there, but the game is great to play, with the difficulty scaling across maps hope to see more maps dropping in and potentially other content into the game. 9/10
