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 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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.

Pretty extraction looter shooter! This lovely game is certainly worth your time and the devs are constantly showing it love with free updates. 10/10
Awesome game!
Figured this was something akin to stalker, surviving alone in a dangerous place, but it's closer to a MMO, where nothing is scarce and you just loiter for a while. Gameplay is usually solid and engaging, where every weapon drastically changes the playstyle, you have to adapt to different enemies and learn to aim in a 2d game. PROGRESS Talking about RPGs, it has the full package, game changing skills, equipment grind, base building and questlines, asides from a couple of very rare items, this goes by pretty quick, story isn`t anything amazing but I enjoy the faction themes (most of them are 1-2 stalker factions combined) GAMEPLAY Good, a somewhat small arena where you fight for survival for ~10min per run, without proper strategy it's fast and brutal, it never really gets easy. Enemies are somewhat dumb, run into their own grenades and just stop moving at the edge of the screen, night battles are way too easy since you can spot their flashlights from way too far while they can`t target you but sometimes they actually press their advantage and force you to make skillful moves. GRAPHICS While I enjoy pixel art, this one feels a bit too simple, humans in particular being comically small, with some degigns being too flashy for the setting, kinda like a minecraft mod, there are some mods that help with this and you get used to amongus nugget people. MISC [list] [*]Found a few critical bugs but nothing that can't be fixed by devmenu (ctrl-alt-P) [*]Had some heavy FPS drops near the end with no apparent cause, [*]Lacks some quality of life features like UI customization, more music and more content on modules. [*]When development was starting, the developer asked reddit how to "verify ownership" for this (gamemaker) project, the game seems to rely on steamDRM to this day, with no signs of actually making a DRM free release. [*]Unfortunately they seem to avoid linux like the plague (proton cope), I wish they would make a native binary but this is probably one of those times devs stall by posting "maybe on a future release" and never actually update gamemaker enough.

Really neat little game, even though it's a 2d pixel art game it still captures the STALKER vibe really well. The desolate atmosphere, unforgiving gameplay that punishes carelessness but rewards caution and preparation.
good
보조 모니터로 하면 마우스 조준선이 튀어서 게임 진행조차 못하네요 알아보니 오래된 버그라는데 어이가 없을뿐입니다 (보조 모니터를 주 모니터로 설정하고 플레이 했습니다 개인적으로 덕코프는 액션겜 느낌이던데 제로시버트가 제 취향에 더 잘 맞네요 강추합니다~)
The game appears simple on the surface but actually has the depth of a STALKER game. I got hooked!
ah
Experiencing SEVERE frame drops whilst navigating menus, during raids and while on the hideout. Tried lowering every possible graphic setting available and it did absolutely nothing. My cpu usage is about 30%, gpu sits around the low 20% mark as well. Won't touch this game until devs fix this EDIT: Devs were really supportive and tried helping me solve my issue! Turns out my gpu is ♥♥♥♥ and its my rigs fault. Will update once I upgrade my cpu
Wenn du hardcore spiele magst ist das ein 10/10
