Publisher Hooded Horse announced that Sandustry sold more than 100,000 copies in its first Early Access week. At the same time, the community shipped an early co-op mod named SandTogether on the Steam Workshop.
First-week numbers set the ceiling for how much guides, wiki coverage, and modding activity a game will sustain during Early Access.
Sandustry launched into Early Access on August 13, 2026 on Steam, GOG, and the Microsoft Store, plus PC Game Pass from day one. Passing 100,000 paid copies in one week, on top of Game Pass players, means the guide demand for basics like the first gold loop and water circulation will stay high for months.
The game holds an Overwhelmingly Positive rating across more than 2,000 reviews, even though the launch build shipped with crashes that the developer has been patching quickly. Retention, not just sales, is what keeps a wiki useful.
v0.5.3, v0.5.4, and v0.5.5 arrived on August 14, 16, and 19. If you hit a bug, check the latest patch notes before troubleshooting, because many early issues are already fixed.
Sandustry is single-player only in the official build, but an early co-op mod named SandTogether is already on the Steam Workshop.
SandTogether adds multiplayer to Sandustry before the developer has published a proper modding API. Treat it as an experiment: expect rough edges, and do not rely on it for long-term saves.
Per the official update notes, subscribed mods only load on the separate “mods” Steam branch. The developer warns that this branch is unstable and not up to date with the live build, so stay on the default branch if you only want to play vanilla.
The developer is building the game with modding in mind, from small visual changes to custom maps, buildings, and production chains. The later Modding and What's Next update is the best current read on branch status while stable support is still taking shape.

Sandustry opened Early Access with strong first-week demand, and community multiplayer experimentation started almost immediately through SandTogether.
Long-term sales, official multiplayer plans, and whether a co-op mod stays stable all still depend on future patches and developer support.
Yes: the milestone summary states more than 100,000 copies sold in the first Early Access week.
No. SandTogether is a community co-op mod on the Steam Workshop, not an official built-in mode.
