Heavy Gear Blitz! Shields of Freedom

From the publisher:

In the vast Badlands of Terra Nova, people are caught between two superpowers bent on dominating the planet. Peace River, Port Arthur and various smaller settlements are fighting for freedom, survival, and sometimes even money. Brought together by a common need, the peoples of the Badlands stand wary, ready to defend themselves and fight for what little they have. But it remains to be seen if these Badlanders will remain free or if the superpowers will crush these people between them in the madness of war . . .

Shields of Freedom contains everything you need to know about the forces of the Badlands including:

Overviews of the major Badlands Factions of Peace river and Port Arthur.

Backgrounds on all the major war machines.

In-depth field guides for the Peace River Defense Force, Port Arthur Korps, and Leagueless Badlanders.
