What is ZERO Sievert?

This top-down, single-player extraction shooter takes place in a fictional post-apocalyptic Eastern Europe. You leave a bunker to explore procedurally generated maps, fight enemies, collect equipment, and extract alive, then trade loot, modify weapons, and improve your base and skills between runs.

For you if...

  • +you want a difficult extraction loop without PvP
  • +you enjoy careful combat where mistakes can end runs
  • +you like loot, weapon modification, and base progression

Not for you if...

  • −you want multiplayer or cooperative extraction runs
  • −you dislike punishing combat and trial-and-error learning

What players say

82% of 15,355 reviews are positive · 81% of 132 in the last 30 days

Players praise the satisfying gunplay, high-stakes solo extraction loop, and depth of the loot and weapon systems. Common complaints focus on clumsy inventory and UI design, poor controller aiming and navigation, and late-game enemies with overly accurate, fast reactions.
