ZERO Sievert v1.2.70a

ZERO Sievert drops you into a gritty, fictitious post-apocalyptic Eastern Europe where nuclear fallout and mutated wildlife are the new normals. As a lone hunter, you operate from a makeshift bunker stocked with traders, crafting and modding stations, and personal quarters. From there, each expedition into the irradiated wasteland is a high-stakes run: you start with little more than a basic firearm and a bottle of water, and it’s your job to scavenge gear, eliminate threats, and—crucially—make it home alive.

Procedurally generated maps across six distinct biomes ensure every foray feels fresh. Dismantle bandit camps, dodge deadly weather, and learn to exploit each environment’s secrets if you want to stay one step ahead of the dangers lurking around every corner. Back at your bunker, you’ll invest resources into base upgrades, trade for supplies, and tinker endlessly with your arsenal.

ZERO Sievert’s deep progression systems let you personalize both guns and your hunter’s abilities. With over 50 weapons and 150 mods, you can fine-tune reload speeds, damage profiles, scopes, grips and more to match your playstyle. The Weapon Skill System lets you level up different armaments—unlocking perks like faster reloads or improved recoil—while hunter-level perks boost your overall survivability, mobility, and crafting prowess.

Faction dynamics add another layer of choice. Will you pledge yourself to the Green Army, fighting to restore order, or to the Crimson Corporation, whose technological might could reshape the wasteland? Gaining reputation unlocks unique missions and high-tier faction loot. Meanwhile, over 100 scavengable items fuel crafting, quests, and trade, gradually revealing the lore of a world broken by fallout.

Finally, robust Steam Workshop support means the community can introduce new weapons, factions, NPCs, questlines and even languages—extending the game far beyond its core content. Whether you’re a solo scavenger or a budding modder, ZERO Sievert offers a tense, endlessly replayable hunt for survival in a beautifully ruined world.
