Approximately Up Mods & Steam Workshop: What Is Official

Two different things called mods

Search demand around this game lumps them together, but they are not the same and they behave differently:

Steam Workshop is official. It is listed in the game’s Steam categories alongside Steam Cloud and Steam Achievements. It is where players share ship blueprints — designs built from blocks the game already has.

Code mods are unofficial. No developer post has announced a modding API, and none of the game’s twelve August 2026 patch notes mentions supporting third-party mods. What exists in that space depends on community loaders and patchers, which is a different reliability proposition entirely.

The official side: Workshop

Three patch notes describe how the Workshop actually behaves:

• Patch 1.0.010 fixed the “Most Popular” sorting filter, page loading and missing results. The old symptom was specific and confusing: when searching, it often looked like the first page was skipped and pages 2, 3, 4, 5 loaded instead.
• Patch 1.0.005 added an option to disable the in-game Workshop for players who would rather not have it in the interface.
• Patch 1.0.007 fixed the Fuel Analyzer mode knob not being saved in blueprints, which affects any shared design saved before August 9, 2026.

Sharing a design through the Workshop is covered in full in the blueprints guide.

The unofficial side, and what it depends on

Community code mods for a Unity-family game generally need a loader — BepInEx is the common one — that injects code at runtime. That approach works, and it also means every mod is one patch away from breaking, because it depends on internal structures the developer is free to change.

Given that this developer shipped twelve patches in 26 days and has committed publicly to at least three to five more years of significant updates, that is not a hypothetical risk. It is the expected cadence.

Two practical consequences:

• Expect breakage after patches. A mod working on 1.0.104 may not work on 1.0.110.
• Nothing here is supported. A bug report from a modded install is not a bug report the developer can act on, and multiplayer between a modded and unmodded client is not a case anything has been tested against — patch 1.0.005 added a message for plain version mismatches, which is a different situation from a modded one.

What you may not need a mod for

Several things people go looking for mods for now ship in the game:

Before installing anything that risks breaking on the next patch, it is worth checking the updates page for whether the feature you want has already shipped.
