Wanderburg Release Date — Steam Early Access

The official Steam store and launch announcement place Wanderburg’s Early Access release on September 8, 2026. This is the confirmed date for the live Steam EA release in the collected evidence. It answers the common search for when the current playable version became available.

The date should be read as an Early Access launch date, not as proof of a finished 1.0 launch. The current official material describes the game as Early Access. A final release date is To be confirmed because no collected official source states one.

For Wanderburg, the confirmed release event is the move into Steam Early Access. The current store frame describes a fully playable core loop with a mobile castle, different biomes, multiple difficulty levels and modular build experimentation. That is the product state attached to the September 8 date.

Early Access is therefore not a hidden 1.0 promise. It tells a player which version boundary to use when reading a guide or patch note. If a page predates September 8, label it pre-release or Demo-era context rather than current EA guidance.

The official Steam listing names Randwerk as the developer and Sidekick Publishing as the publisher. These are the credited companies attached to the store page for the Early Access product. They are included here because release-date searches often ask whether the date belongs to the same game listing.

The credits do not add information about a 1.0 schedule, future platforms or a roadmap. Do not infer those details from the developer or publisher names. Any such announcement is To be confirmed until it appears in an official source.

The official launch announcement says the Demo was retired at the Early Access launch because it no longer represented the game in its new state. That makes the Demo a historical pre-release surface rather than a second current edition. The September 8 EA launch is the later status boundary.

An older Demo listing recorded a February 23, 2026 Demo release. Keep that date attached to the historical listing. It does not replace the EA release date and does not establish a current Demo download route.

The current store description presents Wanderburg as a castle on wheels moving through a medieval world. It describes consuming villages and fortresses, expanding the castle and assembling a modular arsenal. It also names cannons, arcane towers and explosives as examples of build directions.

The same description names multiple biomes and difficulty levels. It lists Modules, Vehicles, Artifacts and Captains as between-run systems. These are broad current product facts, while exact values, unlock order and complete rosters remain To be confirmed.

A pre-release page may use future tense, Demo language or an earlier feature description. Check the capture date before using it. The official September 8 launch announcement is the source that resolves the current transition.

Do not merge an old estimate with the confirmed date as if both were current. If an older page names an unverified 1.0 window, a platform or a feature migration, keep it out of the public answer unless a later official source confirms it. The collected evidence does not provide those confirmations.

No final 1.0 date is stated in the collected official Steam store or News material. The confirmed status is Early Access from September 8, 2026. That is the complete release-date answer supported by the current evidence pack.

A future official announcement could change this page. Until one appears, the final 1.0 schedule is To be confirmed. Avoid substituting a community estimate, search snippet or third-party listing for an official date.

Write “entered Steam Early Access on September 8, 2026” when you mean the current launch event. That wording preserves both the date and the product phase. It avoids making a reader think the date is a final 1.0 release when the official material says Early Access.

If you are discussing the old Demo, use its February 23, 2026 release date and call it historical. The two dates refer to different public surfaces. They should not be combined into one undifferentiated release timeline.

Check the official Steam listing and the dated launch announcement together. The listing identifies the game, developer and publisher, while the announcement explains the Demo retirement and launch context. Using both prevents a name match from becoming a false release claim.

Then check whether a newer official News item changes the status. The collected evidence includes dated 0.9.6–0.9.10 Hotfix posts after launch, but it does not announce a final date. A later status change is To be confirmed until an official source states it.

The September 8 date does not promise a particular future roadmap, platform list, player count or balance state. It confirms when the current EA product became available on Steam. All of those other questions require their own official evidence.

It also does not make every pre-launch claim false or every EA detail permanent. A Demo statement can remain historically accurate, while a patch can change a player-facing interaction. Keep each claim attached to its source date and version.

For current access, follow the official Steam store listing for Wanderburg. The current page is the route tied to the live Early Access state. The retired Demo should not be used as the current product path.

For changes after launch, check the official Steam News feed and use the post date or version label. This is especially important in Early Access, where a dated hotfix can change an instruction without changing the original launch date. Unlisted changes are To be confirmed.

Wanderburg released into Steam Early Access on September 8, 2026. Randwerk is listed as developer and Sidekick Publishing as publisher, and the official launch post says the Demo was retired. The final 1.0 date is not confirmed by the collected official sources.

Use the current Steam page for access and the official News feed for dated changes. Treat September 7 and earlier materials as pre-release or Demo-era evidence. That version boundary is the safest way to keep an Early Access answer accurate.
