The Yet Another Zombie Survivors release date for version 1.0 was August 20, 2026. Steam, GOG, PlayStation 4, PlayStation 5, Xbox One, and Xbox Series X|S launched in that group, while Nintendo Switch was announced for later without an exact date as of August 25. The August 19 developer release article describes the launch content but should not be confused with the August 20 store release date.
Official version 1.0 release date
August 20, 2026 is the formal version 1.0 date shown by the collected Steam and Xbox stores and confirmed by the developer announcement. That agreement across primary sources makes it the date to use in titles, timelines, and platform summaries. Do not substitute a news-post publication date for the day the stores released the game.
The developer had announced the date on July 22, 2026. A later full-release article appeared on August 19, immediately before launch. Those dates are announcement milestones, while August 20 remains the product release date.
Platforms released on August 20
Steam and GOG launched the PC version in the official release group. PlayStation 4 and PlayStation 5 also launched, alongside Xbox One and Xbox Series X|S. These platforms should be described as released rather than planned.
Check the local store for current price, region, and promotion because those commercial details can change. The date and supported hardware come from the official listing, while a temporary discount does not belong in a permanent release summary. Use the platforms guide for the verified capability labels.
Nintendo Switch timing
Nintendo Switch was not part of the synchronized August 20 launch. The developer said the port would arrive shortly after the initial version 1.0 platforms but did not publish an exact date by August 25. 待确认：the final Switch date requires a newer official announcement or verified Nintendo eShop listing.
A post-launch community reply mentioned a hoped-for late-September target. That was a planning window, not a formal date, and must not replace the undated official status. The Switch guide records the distinction and filters similarly named Nintendo games.
Early Access to full release
The collected developer material says the game reached version 1.0 after about three years in Early Access. The developer compared the amount of 1.0 content to roughly four regular major updates. That description explains the scale of the transition without inventing an Early Access start date absent from the research summary.
Older guides can remain useful for stable movement or build principles, but their progression structure, values, roster, and rankings may be incomplete. Version 1.0 adds systems and balance changes that require current verification. Always record the client version when using historical advice.
Ninth Survivor Ranger
Version 1.0 adds Ranger as the ninth Survivor. The official information connects Ranger with a crossbow, animal companions, Critical and Luck support, healing, and the Fear status, and confirms an unlock at Survival Level 175. Those additions make any older eight-character roster incomplete.
Ranger's long-run ranking remains less settled because the character is new. 待确认：community tier placement should wait for repeated same-condition version 1.0 tests. Official identity and unlock facts should remain separate from editorial strength claims.
New arena and mode content
The release material includes Bio Lab and Boss Rush among the main version 1.0 additions. These features expand the available content beyond the older Early Access guides. Their presence does not establish every unlock condition or strategy unless the current game or corresponding research supplies it.
The beginner research also states that Infinite Mode now unlocks by reaching 30 minutes in the relevant arena's Endurance Mode. Older advice tying it to Hardcore completion is not current under that evidence. Use the guide for the ordered progression route.
Camp, missions, and Friendship
Version 1.0 adds Survivors' Camp, main and character missions, and Friendship. The collected guide research says camp missions award Friendship, which permanently increases Cash and Specialization rewards at the end of a run. This makes the camp part of progression rather than only a visual hub.
Story-related achievement work should follow the Briefing Room and Mission Log. The log can show conditions and allow a failed mission to be retried manually. Do not rely on an older achievement guide that predates those systems for a complete version 1.0 route.
Fifth tier and expanded Synergies
Every Survivor receives a fifth tier and additional Synergy and passive nodes in version 1.0. The official structure includes more cross-character interactions and team-wide passive value. This changes the context for character and weapon recommendations made during Early Access.
A current build should verify permanent nodes and in-run card requirements. Character selection alone does not prove that every planned interaction is unlocked. The synergy guide distinguishes official node structure from unverified full combination tables.
Achievements and Torments
The official release adds 88 achievements, including 64 Story entries. It also adds 28 Torments, which are optional high-difficulty challenges and are not required for 100 percent achievement completion. Keep those two groups separate when reporting the scope of version 1.0.
Steam and Xbox achievement totals differ, so the added count should not be used to merge their lists. The achievements guide begins with platform selection and current tracker totals. Store wording remains the final check for a particular platform.
Post-release hotfixes
The collected research records hotfixes 1.0.0a and 1.0.0b after launch. A page verified against one of those builds should name it because balance, compatibility, and exact behavior can change within the broader 1.0 label. This is especially important for mods, trainers, weapon tests, and tier lists.
Record the client build beside screenshots, card text, and results. Do not describe an Early Access value or a launch-day observation as current merely because both belong to the same game. A dated version label makes later corrections targeted and transparent.
The release timeline in one answer
The date was announced July 22, the detailed release article appeared August 19, and version 1.0 launched on August 20, 2026. PC, PlayStation, and Xbox were available in that release group, while Switch remained confirmed for later without a date at the August 25 cutoff. Subsequent 1.0.0a and 1.0.0b hotfixes mean current guides need a more precise build label.
That timeline uses only dates and status present in the collected primary sources. It does not assign a physical edition, Android date, Switch date, or future-update schedule. Update the answer when an official store or developer announcement supplies new evidence.
