Editor

• Now it is possible to annex a part of the ocean and create new land, or annex land selecting "none" and making it part of the ocean.
• When annexing to "none" there is an option to select "uninhabitable", making it empty land instead of ocean.
• Map data such as relief, land cover, economy and population can now be edited directly.
• Ocean border access is now editable, making it possible to customize the regions that can be invaded by sea. If set to "innavigable" connected land cannot be invaded by sea.
• Added sea ice in the artic region as a new ocean border access.
• Lakes and rivers can be created and deleted.
• Borders can be saved and shared as templates, and used as annex regions in other maps.
• Included templates for provinces and historical borders to help as a guide when creating custom maps.
• Country AI personality is now customizable.
• Feuds: establish a custom sentiment towards a country for an AI, biasing its predisposition to attack that country more or less.

Gameplay

• New research options.
• Most researchs are now paired in columns, and developing one limits the maximum development of the other.
• Added new military units.
• Reservist: low cost and maintenance unit that is automatically deployed only to defend your territory.
• Military assets now decline over time. The rate of decay can be reduced by allocating more military funding, and increased if the country can't sustain the minimum maintenance cost of the troops.

New troop recruitment system

• Troop recruitment is now passive instead of active: use a slider for each unit to specify the proportions you wish to be trained in, and they will continuously spawn in your capital.
• Changes will take time to take full effect and actual throughput at each time is limited by available liquidity and recruiting capacity of the country.
• Production capacity is now also limited by the available manpower in the country, and each unit has a different demand for personnel employed.
• Each unit also has different diminishing returns for production rates.
• Troops can also be dismantled instead and recoup part of the cost.

Bonuses

• Morale

  
  Conquering territory, especially if it was previously claimed, can have a positive effect on troop morale, making them more effective in combat. On the other hand, losing territory or being hit by nuclear weapons will have the opposite effect.

• International standing

  
  Actions such as invading, dropping nuclear weapons, breaking truces or neglecting to defend allies will have a negative impact on your international standing, making diplomatic actions more costly. Instead, it can be improved by helping allies defend their territory when they are invaded.

• Combat experience

  
  Fighting battles gives your troops experience, making them more lethal in combat. However, this experience is slowly lost over time or when new recruits join the army.

• Ammunition shortage

  
  During intense battles, ammunition and other supplies are quickly depleted, leaving troops vulnerable if they are not given enough time to resupply.

UI redesign

• Interface graphics can now be scaled with the "UI scale" setting and adjust better to different screen resolutions.
• New main menu layout and background.
• Some interface icons have been improved and changed.
• The background map is now fully customizable and the colors of relief, land cover and ocean depth level can be changed.
• Replaced country colors with more suitable ones.
• Redesigned country troops interface and added slider to choose how automatic paths should prioritize faster or safer routes.
• Added shortcuts to treaties in the country diplomacy interface.
