  • Majorly reworked Espionage. Instead of sending diplomats to carry out sustained spy actions, there is now a new 'Create Spy Network' sustained action, where your diplomat covertly builds up a spy network in another country. Spy networks are size 0-100, and espionage actions other than Build Spy Network are now instant actions that cost a certain amount of spy network points when used but are guaranteed to succeed (for example, Sow Discontent applies the Discontent Sown modifier to the target country for 5 years). Spy Offense modifier was changed to Spy Network Construction and determines the speed at which networks are built, while Spy Defense determines the chance of detecting when another country is building a spy network in your country and disrupting their efforts.
  • 现在就算附庸和他的未拥有核心省份不相邻,你也能将该省份给他了。
  • Added a Loot Mapmode.
  • Study Technology is no longer an action but a discount to technology cost gained from having a spy network in another country with more advanced technology. Size of spy network and how many techs they are ahead of you determines the size of the discount, with only the largest discount for each category used (so if you get 20% land tech discount from one country and 15% from another, your actual discount is 20%).
  • Naval Combat: There is now a chance of capturing ships that would otherwise be sunk, based on Admiral Maneuver skill. (This is in addition to ships with low morale captured after the battle.)
  • 海战:现在损失一艘船就会让整个船队的士气降低。
  • Naval Combat: The Positioning concept is removed.
  • Naval Combat: Introduced "Engagement Width", which is the number of ships that can engage the enemy each turn. This is modified by leader maneuver skill and local/global modifiers.
  • New mapmode: States and Territories.
  • Added the historical_neutral tag which makes countries less likely to become friends or enemies.

  • Merchant marine now gives +50% Sailors & Press Gangs now give +20% Sailor Recovery.
  • Added mechanics for Sailors, given from development in ports. Sailors are used when building ships and repairing them.
  • Added continue button to end game screen to allow you to go beyond the supported end date if not playing ironman.

  • Blockades are now indicated on the map with special border graphics.
