ZERO Sievert Patch Notes — April 30, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
Hello everyone,
Before anything else, we want to say this clearly. Zero Sievert 1 is still a big focus for us, and we’re continuing to support and improve it while we work on what’s next. (As part of that, we’ve just released a new beta that includes a Russian translation!)
With that said, today we’re excited to officially share that Zero Sievert 2 is in development!

For us, this is a chance to take everything we love about Zero Sievert and push it further. We want to build on what made the first game special, keep that addictive extraction loop at the heart of it, and crank up the tension and atmosphere even more.
Most importantly, Zero Sievert 2 is being built with multiplayer in mind from the ground up!
We also know how much the original Zero Sievert means to this community, so we want to be clear that there’s still more coming for it.
For Zero Sievert 1, our current focus is:
Continue QoL and performance improvements
More content! (Weapons, enemies, etc.)
More languages!
We’ll also keep sharing progress with you regularly through Shoe’s excellent YouTube videos and in our Discord.
As for Zero Sievert 2, here’s what we can say right now:
You can play solo or in co-op!
It has a team of seasoned developers supporting it
It has a ✨beautiful✨ 2.5D art style
Did we mention that it’s multiplayer?
We know sequel announcements can make people wonder what that means for the original game, so let us be clear. Zero Sievert 1 is still very much part of our plans.
Zero Sievert exists because of this community, and we want to take this next step with the same honesty and transparency that got us here in the first place.
Thank you for sticking with us, for playing, for sharing feedback (even the negative stuff), and for continuing to support Zero Sievert.
We’ll have more to share on Zero Sievert 2 soon (but not too soon 😉), and we’ll keep you updated on Zero Sievert as well.
