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.
