Space Engineers Modding on OpenMods

Keen Software House's space sandbox with C# scripting

Space Engineers (2013 EA, 2019 1.0) is Keen Software House's voxel space simulation game. The modding architecture is official and well-supported: Steam Workshop integration, in-game Programmable Block C# scripting, the Mod SDK for content authoring.

The catalog covers ship blocks, new mechanics, scripts that control fleets and bases, conversion mods, and quality-of-life additions. Engineering-minded players especially appreciate the in-game C# programming layer for ship automation.

The toolchain

• Steam Workshop: primary distribution.
• In-game Workshop browser: subscribe via game menu.
• Programmable Block: in-game C# scripting for ship automation. Not mods per se but a community-modded interface.
• SE Mod SDK: official authoring tools.

What you'll find on OpenMods

SE mods live overwhelmingly on Steam Workshop. GitHub hosts source for some larger mods. OpenMods catalogues GitHub-published SE mods.

Practical notes

• Workshop is the official channel. No need to look elsewhere for most mods.
• Multiplayer requires server mod parity. Server's mod list is canonical; clients auto-subscribe.
• Performance scales with mod count. Especially mods that add new physics-enabled blocks.
• C# scripting is its own scene. Workshop has thousands of Programmable Block scripts for ship automation.
