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 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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.

compré el juego porque prometia pero las primeras horas son frustrantes. Hay un bug que hace que la mirilla se quede en un lado de la pantalla y no puedas apuntar bien ni nada. Para solucionarlo hay que volver a la base o cerrar el juego (recargar el area vaya), lo cual hace pierdas todo el progreso. Por otro lado, he intentado hacer las misiones de los cientificos, la 1 y 2, y a pesar de tener el analizador en la mochila, al intentar ponerlo me salta el mensaje de "mierda, no tengo el analizador". He tenido que buscar por internet como se hace esa mision y al final en un foro escondido de la mano de dios decian que no te sirve coger el analizador, volver a la base (por estar jodido de salud) porque al volver a la zona, a pesar de tener el dispositivo, tienes que volver a conseguirlo. le tenia ganas y estoy un poco decepcionado con el juego. lo he desinstalado y sin expectativas de volver a instalarlo nunca más. Además, no creo que vayan a solucionar nada de esto porque hace unos meses anunciaron el Zero sievert 2, con lo cual significa que sus recursos van a ir destinados al nuevo juego y este ya esta "abandonado".

One of the best roguelikes I've played in awhile! Automatic recommendation. I will insta-buy any DLCs or sequels. This is an indie take on S.T.A.L.K.E.R. Shadow of Chernobyl...and done very well indeed. Be warned: the initial learning curve is harsher than most games even on normal difficulty (the only difficulty I've played so far). Things happen in real life speed, and there is no hand holding. If you approach an opponent looking in your direction in broad daylight who has a scoped rifle and you don't see them...you will find out about the round after it has ended that run. Nice features: • Vision system (miss the guy with the shotgun behind you and...) • Weather system, day/night cycle, seasons, flashlights, night vision, and much more • Ambient sounds matter. That burst of distant gunfire is from an actual real time map event • Crafting that matters: customize guns, base building • Each run can end instantly...but all that happens is that the game rewinds to before you last left the bunker • All this skilling up and learning to survive, leads to a great middle and late game experience: the painful early days are worth it • Good plot lines and faction reputation system First hard lessons when you start out: • There is no automatic enemy identification for humans out there...the first early deaths are going to be while learning friend from foe • Risk management is a thing: an hour long mission can be blown at the very end with one bad decision, or one missed opponent due to carelessness
Es fehlen viele essenziele Funktionen, die jedes spiel haben sollte die es fast unmöglich machen spaß zu haben. Das beste Beispiel ist es das man keinerlei Feedback bekommt, wenn man schaden erhaltet, ich habe unzählige Male meinen loot verloren, weil ich nicht bemerkt habe das ich in saure stehe oder in Brand stehe… ein Schreien oder ein roter Bildschirm, irgendwas wäre Gold wert, es gibt zwar Modus die das Fixen, jedoch muss sowas standardmäßig integriert sein. Was mich auch enorm gestört hat waren Interaktionen bei NPC die einen instant killen, wenn man was falsch macht OHNE VORWARNUNG, Woher soll ich den wissen das ich eine Tür oder Kiste nicht öffnen darf. Stundenlange Arbeit einfach verschwendet, weil ich ausversehen eine Tür missklickt habe an stad des NPCs, sowas ist einfach schlechtes game designe. ☹ Zusammengefast ist es ein gutes Spiel aber die Fehler mögen sich auch nur für mich so stören sein, sind für mich ausschlaggebend genug gewesen das Spiel zurückzugeben da ich so keinen Spaß haben kann.
I have played the demo before and is one of the best games I have played in years. It takes a little bit of time to get the hand of it but is good. really good.

Very fun, challenging, can be casual, a perfect Steam Deck game, and great with a controller (once you get used to the current control scheme).
COOL IDEA, reliant on luck, the difficulty is just "♥♥♥♥ happens," I can appreciate it a time or two , but ....it's not skill based. You'll find amazing ♥♥♥♥ on the ground, have several great...lucky runs where nothing goes wrong. Then get shot from a bush, fight that off and boar rushes you from behind....and you die with like full plated body armor.. might bruise, but you won't die, so there goes the ultra, "realistic," ♥♥♥♥♥♥♥♥ they were aiming for. It's fun, great idea, but it kinda ♥♥♥♥♥♥♥ sucks the more you play it. Punishing for no reason? Not a stranger to these games, if it's easy it sucks, but this is like the dark souls' gang that thinks thinks complete randomness and no direction = difficulty over skill. This game has direction, trods well, falls right off a cliff from improper mapping. Lose everything over nothing, and its pretty ♥♥♥♥♥♥♥ dumb honestly. cool idea and horrible execution.
- Green Army General order me to Kill Igor. - I refuse and join the Crimson Corp. - Green ♥♥♥♥♥ start to shooting me in all Maps. - I start to ERADICATE every Greem ♥♥♥♥ in any map. - I can't kill the General. - I'm Sad. - Mr. Junk and is friend Grigory are still happy friends. - Igor still alive. Score: 9/10 I want to kill General Artemovich.
