What is ZERO Sievert?

This top-down, single-player extraction shooter takes place in a fictional post-apocalyptic Eastern Europe.

+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

85% of 15,554 reviews are positive · 83% of 248 in the last 30 days
