Activation Details
Write new alternate histories of the globe’s most dramatic conflict in Trial of Allegiance, a new content pack for Hearts of Iron IV. Explore and dominate a world where the strife of the Second World War threatens the safety and security of South American nations. Build a regional superpower to counter the rising global powers, or join the war early, taking your chances with one of the major ideological blocs. South America is rich in resources and manpower - can you lead Argentina, Brazil or Chile to a glorious alternate future?
Hearts of Iron IV: Trial of Allegiance includes:
National Focus Tree for Brazil: Challenged by a decade of internal strife and constitutional crises, Brazil can follow the historical path as a late but valuable member of the Allied cause. Alternately, seek continental hegemony under a new government with new priorities.
National Focus Tree for Argentina: Rife with corruption, revolts and worker unrest, Argentina presents a difficult political challenge. Once you’ve settled the problems at home, you can contribute more on the world stage and help this nation reach its full potential.
National Focus Tree for Chile: Chile is a vigorous republic with a radical tradition that must face domestic fascist parties, the embers of ethnic unrest and the imposing influence of the United States. Chart a course of equality and renewal, rallying under the banner of continental unity.
Paraguay and Uruguay: Minor content as well as several new releasable nations.
New Art: New 3D unit sprites for the Brazilian army, as well as new unique 2D art for National Focus trees and units
