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.

2Dルーターシューティングで放射能で汚染された世界で敵対勢力や化け物を相手取り、世界の真相に迫る というシナリオ シナリオ部分はフレーバー程度なので特に触れないがゲーム部分についてはかなり面白かった、2Dだからといって緊張感がないわけではなくとても良くできている、操作性もパッドで十分なくらいに◎ ただ面白くはあるが粗が目立つのも事実、戦利品のバランス(重量、レア度、金額)が取れていない、一部は基地の改良に使用するが、いかにも高そうなものだと思って持ち帰ったらびっくりするくらい安かったり モンスターからの素材は重量と手間が全く見合っていない、後半に出てくる中ボス扱いの敵も同じ ステージが全部で6面まであるのだが、基本的にルート品は序盤からラインナップがほとんど変わらない しいて言うなら武器やアタッチメント、アーマーくらいなもので新しいマップにいってもそれくらいしか楽しみがない またPVEなので仕方はないのだが後半になるほど敵の殺意が跳ね上がり、視界外から撃ってきたり、角待ちSGなんて芸当もやってきたりする ここらへんは緊張感の兼ね合いもあるから仕方ないかもしれないが、PL側の索敵能力が貧弱なのでもう少しダメージを落とすとか近くにいると呼吸音が聞こえる、銃器を触る音が聞こえるなどしてほしかった 他にも細かい不満点は色々あるが、なんだかんだ最後までいい塩梅で緊張感を持ちながら遊べたので総合的には非常に楽しめたゲームだった 次回作も出るようなのでぜひ購入したい
I'm beyond impressed by this experience. Just when you thought you've seen everything 2d gameplay had to offer. These guys really hit it out of the park here. This is the definition of a hidden gem.
Tarkov but without the ♥♥♥♥♥♥ devs, ♥♥♥♥♥♥ players, ♥♥♥♥♥♥ design choices and ♥♥♥♥♥♥ community. Only thing I don't like is the analyzer missions not having a marker exactly where you're supposed to place them. Runs great on Steam Deck, but should be played with a keyboard and mouse instead of controller.
Si
its fine
Stalker + EFT + Hotline Miami = Zero Sievert Unfortunately the combat is so rng based that I can't recommend it. I've tested this out. Some random low level bandits will literally laser beam you with ♥♥♥♥♥♥ ammo whilst you're wearing at least level 4 armor and using BP against their tier 2-3 armor. Other bandits will repeatedly mag dump you and miss like 90% of their shots as you stand in front of them and let them shoot you. Better yet, you're on your way to the extract and out of absolutely nowhere 3 boars spawn like 2ft away from you and sprint at you at mach ♥♥♥♥ and somehow one of the boars manages to kill you in about 1-2 hits while you're at full health with level 4 armor that has 30% melee damage reduction... This is terrible game design. I was excited for Zero Sievert 2 but the AI make this "game" feel more like a gambling sim than an actual skill-based shooter. Then there's the issue where the AI can literally spawn on top of you or aggro you from out of their LOS that manages to make the game just that much more frustrating and time consuming than it already is. Overall the gameplay and mechanics are inconsistent and it just isn't fun after like 2-3hours. Game crashed and completely froze my pc twice.
I bounced off this a while back but finally gave it a chance and it is exceptional
Great game. At first I was a bit put off by the graphic, it just wasn't my style. But after I keep pushing through, the game really opens up and got way more fun. This game is just brutally hard and I love it. Even at high level, you can still get wrecked fairly easily if you're not careful. The story is a bit lack luster though, I just didn't really care much about the story. Can't wait for Zero Sievert 2
Perfect. Now Marauders is gone, I play this cosy tarkov/stalker. Got used to the top down view instantly. It's all in the imagination...Love it. ❤️
Tarkov and Stalker had a baby.
