Steam Workshop
Last updated: 2026-07-09
Circuit Keep supports the Steam Workshop through the CIRCUIT LAB, the in-game build and test lab. Design a lattice of your own, publish it in one step, and other keepers defend it. Lattices you subscribe to show up in your game, ready to play.
- Build a lattice Open the Circuit Lab, lay out wires, breach points, and terrain, and playtest as you go.
- Publish to the Workshop Share your lattice in one step, update it in place, and jump to its Workshop page from in-game.
- Play shared lattices Subscribe on Steam, find them under CUSTOM LATTICES, or swap files directly.
A Workshop item is the circuit board itself. Shared lattices are played in endless mode, so the intrusion waves are generated fresh each time. Your layout is the puzzle.
