The Steam Next Fest demo for Hull Rupture contained a tutorial level, one starting ship and two game modes — Classic and Trade — and the developers kept it live after the festival so people who missed the event could still play. It was taken down a few days before the full release, because the demo build had become significantly outdated and no longer gave a good impression of the full game.
What was in the Hull Rupture demo
- A tutorial level.
- One starting ship.
- Two game modes: Classic and Trade.
That was it, and the demo was also the only public build of the game for most of its life. The demo also had its own progression rules, which caught out a lot of returning players on the way in — the demo progress guide covers those.
The three demo updates that shaped the launch build
The demo was where most of the current systems were introduced or reworked, so its content was never the same as the launch build:
- September 14, 2026 — a major update adding Hull Construction and a reworked post-battle shop, along with converter Auto, turret relocation and a current-rate Info Mode.
- September 25, 2026 — patch v0.10.12, which added the Rat Turret and changed how module kits are randomized.
- October 22, 2026 — Devlog #4, explaining the hull construction rules in detail.
Each of those still shapes how the launch build plays. The changes since the demo guide lists everything the launch build changed on top of them, including the old advice that no longer holds.
The demo's own progression rules
When the September update shipped, it unlocked the no-combat mode and all previously available artifacts for players of the earlier demo, and marked the tutorial as completed. The newly added artifacts stayed locked, and the new tutorial step explaining Hull Construction did not start automatically.
That last one has a permanent afterlife: the old completion flag suppresses the new step, so a returning demo player who wants the Hull Construction explanation has to switch the tutorial back on in General settings. The tutorial guide has the details, and the demo progress guide lists the two things that actually transfer to launch.
Why it was taken down
Konfa Games' game designer confirmed in the Steam discussion that the decision had been made a long time earlier, because the demo had become significantly outdated and no longer gave a good impression of the full game — and that the team simply forgot to announce the shutdown in advance.
The practical consequence is that the demo is not a way to preview the game in the final week. The release guide covers the launch date, price and platforms.
