ZERO Sievert v1.2.70a (upd.07.06.2026)

ZERO Sievert is a game set in a post-apocalyptic environment and procedurally generated locations. Taking control of the survivor, you have to complete one task to stay alive. The environment is filled with strong opponents, and cities and villages have been reduced to ruins. However, many zones are still alive, and the remaining people are trying to restore society, creating factions and groups. The adventure begins in a bunker, after which the central character goes outside and is free to roam around an open and randomized world. Loot and useful equipment is found in all locations. The stronger the opponents in a certain zone, the better the loot here.

The inventory has a limited number of cells for storing items. The client needs food and drinking water. Medicines restore lost health and provide temporary bonuses. Each weapon type consumes different ammo. At the same time, the hero can carry several types of weapons, and use only 2, but change them as needed. The arsenal includes modern types of firearms: assault and sniper rifles, machine guns, pistols and shotguns. Additional modifiers like scopes, larger magazines, silencers and grenade launchers improve the characteristics of items.
