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 killed a homeless person behind an Arby's in 2001
A shame that we decided to spam promotions from the second game on the first game. I don't want you to make a second game, I want you to fix/finish the first. 'Its happening' was teased almost two months ago, we've gotten a localization hotfix, QoL patch and a hotfix for the hotfix. Why can't you just focus on making a good game rather that just 2/3 unfinished games? Buggy, and clearly not going to get the love it needs to polish it properly. Really disappointed, yall had such a gem but you had to smash it to sell the fragmented pieces.
just yes lol amazing game
it wants to be hardcore like tarkov and stalker but most of the time you'll die to stupid ♥♥♥♥
Such a fantastic little game combining the best part of STALKER, Fallout, Tarkov and lots other in a package so small and lightweight. The community is nice and supportive, and the mods available out there is guaranteed to get you more time out of this. Devs are communicative and respectful too. Absolute give them a try, folks.
You're going to take damage from the same things over and over, and it's never going to become avoidable with skill. Enemies all have aimbot + nightvision and will lock onto you as soon as 1px of them is on the screen.
Just get it.
This game is great for Steam Deck. Works decent and have decent controller support. Some things like inverntory management are not that good, but it's not a dealbreaker. As a whole it's a good single player extraction shooter, a bit tactical, you die a lot and I really hate the fact that your weapon can jam randomly, however you can disable it from the options. Also has mods. Don't be fooled by the graphics, the game is really addictive.
dont think i like the magical parts in a game like this (ghouls and magic crystals)
Its so hard
