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.

It is a harder game than it looks if you are a loot horder. I try to min-max every time but I understand this game doesn't work like that.
To keep it short, I’ve used a pirated copy of your game before—I’ll skip the praise. Although your price tag far exceeds the actual content volume, I still bought it at full price. We players hope you can develop more meaningful content, which would also make it easier for us to recommend it to others. Currently, the price doesn’t justify what the game offers, and that’s its biggest drawback. That’s all I have to say. 游戏总的来说作为小体量游戏是不错的,在一些细节方面,如环境效果和AI战斗逻辑是不错的,但内容和价格不匹配,不建议原价购入。

This game scratch my itch to play some 2d game shooter game, i always want to play this kinda game after playing Terraria and Noita. The map was great, the diffuclty not as hard because i'm playing rookie XD, Weapon type has a great collection of it. What this game lack is some meaningull quest, it's just so much repetition on the quest and it become boring. Overall 7.2/10
Was Excited to play ZERO Sievert, Got it as a gift. When initially trying to launch the game I was met with an error message that win 32 function had failed. as I soon discovered this is a common occurrence, With many different error codes. after a little over an hour of navigating through files and checking drivers, ZERO luck in finding a solution. ill be refunding it. probably a great game but it doesn't even give you the chance to discover that. Edit: after some time to cool off, and an encouraging response from the developer trying to determine the cause of this issue. ill be changing the review to a positive review, for the sole purpose that a dev that cares enough to respond to a reviewer with problems deserves to be recognized. still think this game has the potential to be one of my "go too" solo games, now I have a reason to get it to launch and find out. Update: after dev response, I redownloaded the game and it worked as originally intended. not sure what has changed as I uninstalled the game multiple times during the initial troubleshooting process. credit to shoe for responding to a frustrated customer and giving negative reviews the time of day. if it wasn't for that my review would have never changed and I would have never given this game a second chance, that's how you save a customer. <3
