ZERO Sievert (PC) – Steam Gift – GLOBAL

Overview

ZERO Sievert is a tense top-down pixel-art extraction shooter from solo developer Luca Carbonera at CABO Studio, set in the radioactive wasteland of post-apocalyptic Eastern Europe. You play a Hunter operating out of an underground bunker, heading into procedurally generated maps to scavenge loot, gun down bandits and mutants, then make it back alive before fatigue, hunger, or a stray round ends the run. Built for solo players who love STALKER’s setting and Tarkov-style risk-versus-reward gunplay, it pairs deep weapon modding and base building with permadeath-adjacent extraction tension in a tight, replayable package.

What’s included / why buy

• Full 1.0 release: a ZERO Sievert Steam key that unlocks the complete game, including the Zakov City endgame zone and the full story.
• Six procedural biomes: Forest, Mall, Makeshift Camp, and beyond — each map generates new loot locations, hiding spots, and layouts every run, so no two extractions play out the same.
• Deep gunsmithing: over 50 unique firearms and more than 150 attachments and mods, with ammo choices that genuinely change penetration, damage, and recoil — praised by PC Gamer as “some of the most sophisticated gunsmithing” in any game.
• Bunker progression: trade with NPCs, upgrade modding stations, build out your base of operations, and follow multiple questlines that gradually unravel the lore of Zakov.
• Steam Workshop: install community mods that add new weapons, factions, NPCs, quests, and languages — or share your own creations with other Hunters.
• Steam Deck verified: the game is officially rated as playable on Steam Deck, ready to take on the go without configuration.
