First official public screenshot of HoI4's map & interface, from the 7th February 'Our Vision' dev diary

The map is where most tactical and strategic decisions happen. It also provides information related to these purposes, such as, weather, air combat, land combat, naval combat, and buildings.

Map divisions

The Map can be divided into three subdivisions:

• Provinces are the smallest subunit of the map. It is here that terrain, weather, capitals, land combat, supply, and victory points are handled.

• States are the next smallest subunit of the map, where construction, manpower, population, and country borders are decided.

• Strategic Regions are the largest of the subdivisions, and are where naval combat and air combat occur.

Map modes

The map mode icons.

Using different map modes, you can alter the information presented on the map. These map modes can be activated by either clicking on the appropriate button (icon) located in the lower right corner of the main screen or by pressing the associated hotkey. Additional map modes can be revealed by clicking the arrow button.

Additional map modes.

Default map mode

File:Default map nogui.jpg

The Default map mode without the day/night loop.

Shows sovereign nations and armies.

The default map mode is a combination of the political map mode and terrain map mode from previous games. It shows the name of all the nations, with their political color. Zoomed out, mainly the nation's color is seen, however, when zooming in, the terrain becomes more and more visible, integrating both map modes into one. Air fields, naval bases, capitals, and almost any other object on the map can be seen in this mode, represented by different symbols:

• Naval bases are anchors Naval base icon.
• Airfields are a top down picture of an airplane.
• Capitals are a star, which can be green if it is the nation's capital, gray if they are any other nation's capital, or red if they are the capital of any of the nation's enemies. All capitals contain victory points.
• Victory points are denoted by either a square, a pentagon, or a circle depending on the value. They are named when zoomed in and follow the color scheme of capitals.
  • square = minor vp (1, 2, 3, or 5 are common)
  • pentagon = medium vp (10 or 15 are common)
  • circle = major vp (20, 25, 30, or 40 are common)
  • star = capital vp (1, 2, 3, 4, 5, 10, 13, 15, 20, 25, 30, 40, or 50 are common)
• Units can be seen as counters or sprites on the map.
• Battles can be seen as pointers that are green if the nation is winning the battle, yellow if the battle is favoring neither side, or red if the nation is losing the battle, and it shows a number that summarizes how much the battle favors one side or the other.
• Naval combat can be seen along with navies and their missions.
• Aircraft can be seen flying where aircraft are in operation.
• Forts and any other state- or province-wide constructions are also visible.
• Demilitarized zones will be a red outline around any demilitarized area. The only time they are used is at the beginning of the game in the Rhineland, Danzig, the Turkish Straits (requires Battle for the Bosporus ) and Åland. An exception is the option to create demilitarized zones (DMZ) during peace conferences (requires By Blood Alone ) .

Strategic navy map mode

The Strategic Navy map mode.

Shows strategic regions relevant to naval activity, with information on naval supremacy and naval tasks.

The naval map mode consists of the world's strategic regions, with a color scheme similar to the diplomacy for states on land under it. Convoy routes are also shown here with the following color scheme:

• Blue trade routes are resource transfers. These are imports, exports or resource transfers from owned oversea resources.
• White trade routes are supply transfers to oversea units.
• Green trade routes are lend lease routes.

Trade routes require convoys to operate.

Strategic regions that have sea provinces will be highlighted with green if they are under allied naval superiority. Provinces that are striped red are out of the fleets' operational range.

Straits

Canals or any type of controlled strait are shown on this map mode, and by hovering over them it is possible to see the access permissions your country has as well as the land provinces controlling the strait (blue outline). Straits are also shown on the Supply Map Mode and the Resource Map mode.

The following, are the names and province control points of the straits/canals on map and their respective permissions granted to nations (depending on the relations with the strait controllers).

Strategic air map mode

The Strategic Air map mode.

• Green, which means the nation or its allies has air superiority.
• Yellow, which means the air superiority is contested.

This map mode also shows all of the air missions currently set with the total number of planes assigned.
In the strategic air map mode more ground crews can be assigned, by clicking the icon in the desired strategic region. This gives a +10% bonus to mission efficiency in the strategic region.
