About This ZERO Sievert 2 Wiki
This is an independent guide and reference site for ZERO Sievert 2. It is not operated by Underdog, Modern Wolf, CABO Studio, Valve or Discord.
What we cover
The initial English edition focuses on official access, the limited alpha, core gameplay concepts, PC requirements and the release roadmap. More detailed walkthroughs should follow only after their steps can be checked in a specific build.
How the information is checked
We prioritize the official Steam page and developer announcements, record a review date and separate released facts from future plans. The source ledger names the material used by each guide. We have not performed a hands-on playtest, so we do not claim first-person testing.
Corrections and independence
If a build changes or a claim is wrong, send the page URL, the exact claim and a direct source that supports the correction. Game titles, trademarks and screenshots remain with their respective owners.
