ZERO Sievert 2 Playtest Access

The closed alpha opened on November 3, 2026. The developer says limited keys are distributed through the official ZERO Sievert Discord server, in its ZERO Sievert 2 channel. Key availability can change without notice.

The official route to a key

The announcement describes this as a small closed test rather than a public download. No key is supplied by this site; we do not link to resale, repacks or third-party installers.

  • Open the Discord invite linked from the official Steam announcement.
  • Join the server and find the ZERO Sievert 2 channel.
  • Follow the current instructions posted there. If you receive a key, redeem it in Steam for ZERO Sievert 2 Playtest.

What this test includes

The official announcement describes approximately the first two hours, five quests, one Forest map and a starting selection of weapons and attachments. It also mentions Bunker activities and solo or cooperative play. This is a development build, so bugs and unfinished systems are expected.

Availability and feedback

The Steam event currently shows an end time of November 20, 2026 in CST, but the developer also says slots are limited and access may not last. Check the official channel for the latest key status before making plans.

After a session, the test is designed to open an official feedback form in the browser. Share bug details through that form or the developer’s Steam discussion space; do not post account credentials or unused keys in public comments.
