From Introduction:
Welcome to the exciting world of Heavy Gear d6! Set on the distant colonly world of Terra Nova, Heavy Gear offers a rich and believable science-fiction setting for fast-paced Mecha action and adventure. Abandoned millenia ago by Earth's government, the colonists on Terra Nova were beset by the dangerous and diverse environmental conditions of the dry and hot planet. Despite this adversity, the proud and tough settlers banded together in polar confederations, developing advanced 4 meter tall walkers, or "Gears," to make the difficult work ahead of them more manageable. Today, the ubiquitous Gears are found across the desert world, whether in police forces, livestock ranches, gladiatorial bouts, construction teams or, most famously, mechanized military regiments. Gears have transformed life on the harsh world of Terra Nova, and colour every aspect of life here.
