Following the fall of the Star League, centuries of warfare have reduced battlefield technology to a fraction of its former level. The discovery of the Helm Memory Core begins to restore lost knowledge, bringing new BattleMechs and experimental systems into service during the Succession Wars. This reference volume presents common units from the era, including BattleMechs, vehicles, and aerospace fighters. Each entry includes detailed artwork, historical background, capabilities, game statistics, and notable pilots.
