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 2,420 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.

i wanted to like it a lot. as other reviews have stated, the core loop seems to be repetitive for me personally. I couldn't justify the 20 dollars because i only spent 20 minutes in the game before it felt like i saw mostly everything. or at least, you know the extent of what the game is going to show you. If you really like situational/survival games, you might like it more than me, but i can just tell it's proc gen events, a character controller, and reps/grinds to the farther progress of the same thing. i wanted to like it, a lot. i'll give it another go, eventually and change my review if anything has changed since my logged hours (near release.) I think the 3d in #2 might keep my attention better. It does feel good to play, just feels like a one trick pony with a 19.99 price tag in my opinion
el juego es bastante bueno pero aún tiene cosas por mejorar. el ejemplo más notorio es la caída de FPS al entrar en zonas medianas y grandes de fuego. algunos problemas de rendimiento son solucionables pero otros son ya incorregibles, sugiero también arreglar ciertas fallas en la traducción al tener palabras con tilde, fuera de eso el juego tiene potencial para más, pero le queda un buen tramo por delante pdt: han considerado añadir un modo multijugador cooperativo? no hablo del tipico pvp o esas cosas, sino un modo co-op online o lan de 2-4 jugadores

its way too good
The game could do with a bit more chiseling, but the gameplay loop is addictive. I played of the easiest difficulty, and wasn't easy, but a perfect balance between challenge and fun. The quests are entertaining (except for the ones from the Networker, those are complete grind), the difficulty progression is very well balanced, same as the content (as soon as an area becomes stagnant, new content is unlocked).
very good indeed
Oh man, I just love when the evacuation zone spawns out of bounds and forces me to die, making me lose all my hard earned loot, including all my armor and guns! So great! To be honest, Im writing this out of the sheer spite i feel right now. Besides that game pretty good.
....im hooked
Estoy agradecido y bastante sorprendido con el cambio y mejora que se ve en el idioma me gusta mucho y ya puedo jugarlo y disfrutar la historia y el juego original con amigos y la comunidad hispano hablante, que aseguro que puede marcar un antes y un despues de como se veia este juego la verdad me gusta, me llama mucho la atencion el parche que esta en beta del juego asi que estare mas activo en el juego. detalles que me gustaria que mejoraran: 1._La lentras que señalan cada lugar y personajes dentro del bunker, siento que son invasivas o mal colocadas que no van con el juego se sientes fuera de lugar o innecesarias (no me refiero a los dialogos de los personajes si no los que estan encima de ellos que los señalan) 2._ El rendimiento esta mucho mejor ya no hay bajon de fps con lluvia o niebla pero ahora me afecta un poco la resolucion se ve un poco tosca pero no molesta del todo, jugare mas para asegurarme de eso. 3._ el sonido de los pasos creo que sigue igual pero realmente creo que mejoror en los otros efectos, el pasto los disparos y las granadas y sus efectos de estado del personajes, aun que los pasos siguen desconsertando un poco, cre que se puede mejorar. y eso seria todo de verdad estoy feliz por el juego y los desarrolladores que escucharon las reseñas y su cominudad que romendaria este juego 100% con los ojos cerrados
Comprato a un prezzo risibile mi aspettavo un giochino semplice e scontato su cui passare qualche ora, invece è una figata pazzesca! La visione dall'alto con il campo visivo evidenziato è un'ottima trovata sia stilistica che di gameplay. Il loop di estrazione è ottimo, i nemici reagiscono con una intelligenza sorprendente, a volte nascondendosi, a volte caricando a testa bassa, cosa che rende la difficoltà del gioco da non sottovalutare. Per i gamer dad come me c'è anche la possibilità di creare una "campagna" senza perdita di loot quando muori. Le armi danno soddisfazioni sotto tutti i punti di vista, dalla cecchinata da lontano al rumore delle smg quando svuoti il caricatore contro l'orrore indescrivibile che ti carica contro. Una vera, piccola perla.
Ok. its rougelike ish. You die you don't lose anything but you don't gain anything either. Maps are always random with a few landmarks. The only thing that doesn't seem to change is where the rail line is when you start the map. Huge amount of guns. inventory management is a thing. As is base building but that's just in the main base. Different modules do different things for you. There are upgrades for you bases inventory that you'll want to do stat. It's basically you, 2 guns slots, armor a backpack and some hot keys that you can put grenades or healthpacks in. The missions mostly boil down to go here and kill this guy. Luckily the land is harsh and theres no guarentee you won't find the guy your hunting dead already. you will get notified that the missions done if this happens but then theres the issue of finding the corpse if you didn't look at the map well before hand. There are 6 zones. Decent variety. Forest, suburbs kinda, industrial port, swamp, a mall and the city. Honestly its worth a look. I decided it was up my alley after i watched a play through on youtube.
