SlashZero Updates

SlashZero is still an upcoming side-scrolling action roguelike from Streetlamp Studio, published by Skystone Games. This hub is the wiki’s news desk: public dates, demo windows, and storefront tags. It is not a live-service patch log. Streetlamp has not posted a full-game patch cadence, and Steam lists the campaign as single-player.

Use the articles below when you need a specific clock time rather than a recap of the whole year.

Demo window (September 2026)

On 3 September 2026, PlayStation’s State of Play showed a story trailer and named a Spring 2027 full launch. The same day, Streetlamp opened a time-limited demo on Steam and PlayStation 5.

• Start: 3 September 2026, 15:15 UTC
• End: 23 September 2026, 15:00 UTC
• Format: data-wipe test — saves are deleted when the window closes
• Length: more than ten hours, including Hamlet and secret bosses
• PC demo: Windows only (Steam demo app 5099550)

Read the demo launch notes for the Steam news recap, wipe rules, and what changed versus the March playtest. The dev stream schedule covers the 4–7 September 2026 broadcast. The demo guide covers how to spend that window in-game.

Full launch window

Steam’s store page still lists Q1 2027. State of Play used Spring 2027. Treat Spring 2027 as the public window and Q1 2027 as the Steam quarter tag until Streetlamp names a calendar day. Announced platforms: Steam (app 4061170), Epic Games Store, and PlayStation 5. No Xbox SKU sits on those pages. Price is TBA.

The release date page compares those labels, lists wishlist steps, and flags what is still missing.

Public timeline so far

1. March 2026 — Future Games Show. Reveal trailer. Streetlamp and Skystone Games introduce Timehackers, shattered timelines, and HIEROS-I.
2. 27 March–9 April 2026 — first playtest. About two hours of content, Nyx and Fina, English and Simplified Chinese audio, Windows only, capped access.
3. June 2026 — PC Gaming Show. New trailer and the first Hamlet tease.
4. 3 September 2026 — State of Play plus demo. Spring 2027 window, story trailer, Hamlet as a progress unlock, secret bosses Erik and Ye.
5. 4–7 September 2026 — Dev Stream. Producer Jun’s team walks Game Intro, three Timehackers, and a future-plan block. See the dev stream schedule.

Older playtest saves do not carry into the September demo. Demo saves do not carry into the full game. If a later Steam news post changes either rule, that post will get its own article here.

How to follow official posts

Streetlamp posts on Steam news, Discord, X, YouTube, and the studio site. This wiki is unofficial; we summarize those posts and keep locale-agnostic links. Bookmark the links hub for store pages and social accounts.

When a future Steam news post names a price, a day-one patch, or a platform change, it should land under this hub as its own page rather than a buried paragraph on an older recap.

What this hub does not cover

SlashZero is not a Roblox experience. There are no Roblox codes, gacha banners, or season passes to track. Combat routing, Blessings, and Timehacker kits live under Guides and Players. Spec sheets and storefronts live under Tools.

If you only have time for two clicks during the September window, open the demo launch notes first, then keep the release date page for the 2027 window.

Streetlamp’s next dated public beat after 23 September 2026 is the Spring 2027 launch itself unless a new test is announced. This hub will stay a date board, not a rumor blog: if a number is not on Steam, PlayStation, or Streetlamp’s own channels, it will not appear as a fact here.
