The Republic Era—better known as the Dark Age—was a time of upheaval and opportunity. Fortunes rose and fell, nations crumbled and others reconstituted. And at the center of the whirlwind lay Terra, the crown jewel of the Republic, a prize waiting for the warrior strong enough to seize it. This volume features some of the most common ’Mechs from the Dark Age. Each machine is accompanied by an illustration, a description of its history, capabilities, and game stats.
