Does Sandustry have co-op or multiplayer?
No official co-op. One dated developer reply, and one community mod that fills the gap.
Quick answer
Sandustry's Steam categories list it as a single-player game, and there is no official co-op or multiplayer mode. The only developer statement on the subject is a reply posted on 5 February 2025, during the demo period, saying multiplayer would be possible but very scuffed, and that building a reliable network model around this kind of simulation is really hard. Nothing published since updates that, so multiplayer is neither announced nor ruled out. A community Workshop mod, SandTogether, describes four players sharing one world.
Steps
- Check the store page's own category list: Sandustry is listed as Single-player, with Steam Workshop as a separate category.
- Read the developer's reply in the 2025 multiplayer thread before treating co-op as planned. It is dated 5 February 2025 and predates every current build.
- Check the newer Multiplayer thread from 15 August 2026 as well. It has no developer reply.
- If you want co-op anyway, open the SandTogether listing on the game's official Workshop hub and read the author's own description and requirements.
- Treat that mod as untested here. This site has not installed or run it.
Requirements / limits
- The developer statement is a reply inside a player thread, not an announcement, and it is roughly eighteen months older than the current build.
- No source says multiplayer is planned, scheduled or cancelled, so this page says none of those things.
- SandTogether's four-player shared-world description is the mod author's own claim about the mod, not a statement about the game.
- Loading any Workshop mod has its own conditions, which are covered on the mods page.
Common mistakes
- Reading the 2025 reply as a roadmap commitment. It is a hedged answer to a question, with a date attached.
- Reading the silence on the 2026 thread as a change of position. It means nobody replied.
- Treating a mod as an official feature because it appears on the game's own Workshop hub.
Still unverified
- Is multiplayer planned for a later build?Not verifiedThe only developer statement is from February 2025 and describes difficulty rather than intent. A newer thread from 15 August 2026 has no reply.
- Does SandTogether work on the current build?Not verifiedThe listing states four-player shared-world co-op. This site has not installed or tested it, and no developer statement covers it.
