Archean Patch Notes — March 6, 2026
Aggregated from Steam, cross-tracked with Battle.net coverage on GamePatchNote.
Hey everyone!
This update introduces a new sensor component, new build elements, and several improvements across the game.
Distance Sensor
A laser rangefinder that measures the distance to the nearest surface, whether terrain or another build. Configurable range up to 25 km, with an optional visible green laser beam. Useful for applications such as altimetry, automated guidance or collision avoidance.
Triangular Mesh Panels
New build element type: triangular panels. Thin panels placed on a 25 cm grid, allowing shapes that are not possible with regular blocks. They support normal smoothing for curved surfaces, such as canopies or cockpit glass. They are airtight and work with the pressurized volume system.
Struts
Thin beams connecting two points in space. They are placed point-to-point and can be painted.
