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.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
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.

Easy to put down for months and come back to another playthrough. Settings can be changed at any time for challenge runs or addons from the mod workshop. 10/10 game for what it's attempting to pull off!
사람이 무서워 탈콥을 못하는 나로서는 괜찮은 게임
Great gameplay loop. Much better than some new AAA productions in this respect. Feels like Stalker married with Escape from Tarkov, but in top-down view.
Amazing
非常好的圣诞老头,使我的子弹旋转
게임 하나 거지같이 만들었네 니같은 놈들이 설치기 전에 덕스코프가 기강 다져놔서 참 다행이다 진짜 이걸 사고 2시간 이상 플레이 안한 사람은 무조건 환불하셈 게임에서 진짜 개똥 냄새 남
This game is just a nice, little fun Stalker-like top-down experience. It scratches that STALKER and extraction itch without loading up something more heavy, usually with many mods - like STALKER 2 or STALKER GAMMA/EFP. It has a nice, clean loop and the difficulty settings feel nice to me, right now I am playing on relaxed. Which feels nice and still provides some good, tense moments when out in the zone gunplay feels good, fast-paced and reactive. Sound design is pretty good too. Controls feel nice, but I will say that I hope that the devs will continue to make gameplay better with a control pad, as this can be a fun experience from your couch or bed. The control pad is... serviceable as of now, but needs more work. I recommend KB/M for this game for now. This is my largest gripe so far. It feels pretty balanced to me so far. You can get overwhelmed quickly, especially if you're impatient and just looking to book it to the extraction zone. This game will punish your mistakes and will punish you for being ill-prepared. You can make your trips into the zone short or long. It all depends on what you find. Forays are probably best at first, and I recommend using the map marker for the extraction points. Otherwise, like with all games, I do recommend going in blind. It is part of the magic of the games that we love to enjoy so much. Performance for me is pretty solid having played at both 2560x1440 and 3140x2160, maxed. It is very lightweight and I have not experienced any stutters thus far. Also a great game to play in the summer months when you don't want to push your hardware too hard and make you office/room/living room hotter than it probably already is.
