Experimental Technical Readout: Periphery

This supplement explores prototype and custom military designs developed by the scattered realms of the Periphery in the aftermath of the Jihad. As these states rebuild and adopt emerging technologies from the Inner Sphere, experimental weapons and battlefield systems enter testing and limited service. The book presents 13 experimental designs, including BattleMechs, vehicles, aerospace units, and battle armor. Each entry includes game statistics and a Record Sheet for use in advanced BattleTech games.
