The Gungnir Space Mine is an aged but highly effective space mine originally developed some time before the Great Galactic War by the Echani Confederation. A Dodecahedron in shape the mine consisted of 12 pentagon shaped sides each with an extending plate. As the plates extended sensor antenna extended out as well. Sensors onboard the mine could detect ships via passive sensors, magnetic sensors, and IFF detection, as well as several other standard forms.
