- 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.
