Description

Build a new empire, resist foreign aggression or explore the limits of neutrality in Hearts of Iron IV: By Blood Alone. This new expansion for Paradox Interactive’s World War II grand strategy wargame adds new alternate history options and gameplay variety for three nations, as well as other significant changes.

Features:

  • New Italian Focus Tree: Follow the historical path of Mussolini's Italy or rewrite history by restoring power to the monarchy, leading a Communist revolution or replacing Mussolini with one of a variety of new contenders.
  • New Ethiopian Focus Tree: Defy the odds to defeat the Italian invader or resist the conqueror from abroad using unique Government in Exile abilities.
  • New Swiss Focus Tree: Surrounded by France, Germany and Italy, the mountain nation of Switzerland finds strength in its neutrality, balancing competing factions and overtures from the great powers.
  • New Peace Conference Options: Demilitarize zones of the map or entire nations, bid on the capital ships of defeated powers, or claim control of enemy resources or factories as reparations.
  • Aircraft Designer: Design and build your own planes, from nimble interceptors that prioritize speed to durable bombers crafted to unload tons of destruction from high above.
  • Unit Medals: A log of each division’s accomplishments lets you track their performance, and even allows you to award unique medals to division commanders for their actions in the field.
  • Embargo Interaction: Embargo your enemies with a new diplomatic interaction, preventing them from trading with you if they have generated enough world tension.

    Must have for added gameplay*****

    The plane designer and the overhaul to Italy make this a must have DLC. The new peace conference options are also a huge improvement.

    One of those HoI IV packs to buy on sale*****

    Good enough to want in your library, bad enough that you can hold out for a sale. I deduct a star for any pack were Paradox gates what should be free updates to certain mechanics behind a DLC paywall. The country packs themself are decent.
