About ZERO Sievert
ZERO Sievert drops players into a post‑apocalyptic Eastern European wasteland where scavenging, combat, and survival are core. Players operate from a bunker hub filled with traders and modding stations, then venture into six procedurally generated biomes to loot, fight bandits, and avoid fallout‑tainted wildlife. Progression is driven by weapon modification, skill trees, and faction reputation, offering varied playstyles and loot opportunities. The game supports full controller use, Steam Cloud, and community‑created content via the Steam Workshop.
01 / THE GUIDE
Procedurally Generated Wasteland
Each excursion takes place on one of six maps whose layouts, loot spots, weather, and hiding places change each run. This ensures that no two journeys feel identical, encouraging players to adapt to new terrain and discover each biome’s secrets. The dynamic environment also influences how players plan extraction routes and manage resources like water.
The ever‑shifting world rewards exploration and careful observation, as familiar landmarks may appear in new configurations. Players must stay alert to both environmental hazards and the unpredictable placement of enemies and supplies.
- Scout the perimeter before engaging to locate safe extraction points.
- Take note of weather changes; they can affect visibility and movement.

Weapon Modification System
ZERO Sievert offers over 50 unique guns and 150 mods that can be combined at the bunker’s modding stations. Players can tailor firearms to suit personal playstyles, focusing on stats such as damage, reload speed, or movement speed. The system allows for extensive customization, turning any weapon into a potent tool for the wasteland.
Mod choices also interact with the Weapon Skill System, unlocking perks that further enhance performance. This deep customization encourages experimentation and strategic planning before each run.
- Balance damage and reload speed to maintain combat effectiveness.
- Experiment with different mod combinations to discover synergistic perks.

Skill Progression and Perks
Surviving encounters grants experience that fuels both weapon‑type skill trees and a hunter skill system. Weapon XP improves reload speed, damage, movement speed, and unlocks unique weapon‑specific perks. The hunter skill tree provides broader perks that aid navigation, combat, and challenge handling.
Leveling these systems unlocks new abilities, making players increasingly effective at extracting loot and confronting tougher foes across the biomes.
- Prioritize weapon types you use most to unlock relevant perks faster.
- Mix hunter perks that improve mobility with combat‑focused weapon perks.
04 / THE GUIDE
Faction Alignment
In the region of Zakov, players encounter two major factions: The Green Army, which upholds law and order, and the Crimson Corporation, a pharmaceutical and technology conglomerate. Choosing a faction grants reputation, unlocks exclusive quests, and provides access to high‑tier loot.
Faction quests deepen the narrative and offer unique challenges, while reputation influences interactions with NPCs and the availability of faction‑specific resources.
- Complete early faction quests to quickly earn reputation.
- Compare faction rewards to align with your preferred playstyle.

Steam Workshop Mod Support
ZERO Sievert integrates Steam Workshop, allowing the community to add new weapons, factions, NPCs, quests, languages, and other content. Players can browse, subscribe, and incorporate these mods directly into their game, expanding the post‑apocalyptic experience.
Mod support encourages a continually evolving world, giving players fresh challenges and narrative elements beyond the base game’s offerings.
