New Campaign

Experience a full new Iron Harvest campaign in single player or side-by-side in co-op in 7 challenging missions with over 25 minutes of new cinematics and dozens of new allies and enemies.

New Faction: Usonia

The American Union of Usonia stayed out of the Great War and became an economic and military powerhouse, unnoticed by Europe’s old elites. Usonia could become a beacon of hope for the oppressed, bringing freedom and justice to everyone, or it could succumb to the temptations of power and become a new empire, ruling with an iron first. The addon features the new faction “Usonia”, the 1920+ version of the US. More than 30 new infantry units, mechs and buildings for these factions.

New Unit Type: Air Units!

Take to the sky and conquer the world with the introduction of new airship units for all factions. These early flying machines come in different classes, from the agile sky bike to the colossal battleship of the Usonian hero Admiral Mason, traversing any terrain and sending death from above. The bravest of men become Paratroopers who perform dangerous missions behind enemy lines. Adapt your strategies and prepare your defenses with new anti – air mechanics for all Iron Harvest factions!
