Hearts of Iron IV is a war strategy video game developed and published by Paradox Interactive. Released on June 6, 2016, it is the sequel to Hearts of Iron III and part of the Hearts of Iron series of grand strategy games focusing on World War II. The game allows the player to take control of any nation in the world in either 1936 or 1939, and lead them to victory against the major powers at the time: the Axis, the Allies and the Comintern

Gameplay

Hearts of Iron IV is a grand strategy wargame that primarily revolves around World War II. The player may play as any nation in the world from 1936 on in singleplayer or multiplayer, although the game is not designed to go beyond 1948. A nation's military is divided between naval forces, aerial forces, and ground forces. For the ground forces, the player may train, customize, and command divisions consisting of various types of infantry, tanks, and other units. These divisions require equipment and manpower to properly fight. The navy and air force also require men and equipment, including the actual warships and warplanes that are used in combat. Equipment is produced by military factories, while ships are built by dockyards. These military factories and dockyards are, in turn, constructed by civilian factories, which also construct a variety of other buildings, produce consumer goods for the civilian population, and oversee commerce with other nations. Most nations are initially forced to devote a significant number of their civilian factories to producing consumer goods, but as the nation becomes increasingly mobilized, more factories will be freed up for other purposes. Mobilization is represented as a "policy" that the player may adjust with the proper amount of political power, an abstract "resource" that is also used to appoint new ministers and change other facets of the nation's government. In addition to mobilization, there are other policies, including the nation's stance on conscription and commerce.

Land in Hearts of Iron IV is divided into tiny regions known as provinces. The major seas and oceans (for warships) and the sky (for warplanes) are similarly divided into different regions. These provinces each have a type of terrain assigned to them that determines how well different types of units will perform in combat there. Divisions are placed in provinces and can attack enemy units in adjacent provinces. How well divisions perform in combat depends on various factors, such as the quality of their equipment, the weather, the type of terrain, the skill and traits of the general commanding the divisions, and the morale of both sides. Technologies can be researched to improve equipment and learn new military doctrines, among other things, which often means that a more technologically advanced nation will have an edge in combat. If a division (or a group of divisions) successfully overwhelms an enemy province, they may occupy it. Occupying key provinces within a state allows the occupying power to access the enemy's factories and natural resources in that state. Resistance to occupation within a state can hamper the occupying power's control over it.

Hearts of Iron IV also attempts to recreate the complex diplomatic relationships of the day. Nations may undertake a variety of diplomatic actions; they may sign non-aggression pacts, guarantee the independence of other nations, and offer or request military access, amongst other things. Another key feature of diplomacy is the ability to create a faction or invite other nations to an existing one. Factions represent the main alliances of the era, like the Axis and Allies (for gameplay purposes, real-world factions like the Axis and Allies are split into numerous smaller factions, like the Comintern, the Chinese United Front, and the Co-Prosperity Sphere). Faction members may assist each other in wars, making faction members very valuable assets. A number of more clandestine diplomatic actions are also available. For example, the player may justify war against other nations, spread their ideology abroad, or stage a coup. Countries in the game may be democratic, fascist, communist, or non-aligned. Each of the four ideologies have advantages and disadvantages; for example, fascist nations can go to war with other countries easily, but other nations are not as willing to trade with them as they are with democratic countries. If a different ideology becomes too popular in a country, a referendum may be held that will peacefully convert the nation to the more popular ideology. Otherwise, ideologies may come to power violently through coups, civil wars, or forced subjugation by a foreign power.

While Hearts of Iron 4 does feature some scripted events, the game features a "national focus" system that makes fixed events less necessary than in previous installments in the series. Each country in the game has a "focus tree" with various "national focuses" that grant certain effects or trigger events. For example, in order for the Anschluss to occur, Germany must first complete the focus that is related to it. Other focuses can grant special bonuses, like faster research times for certain technologies or extra factories. While some bonuses (like extra factories) are very tangible, others (like improvements to morale) are more abstract. These abstract bonuses are represented by "national spirits" that can be temporary or permanent. Not all national spirits are granted by focuses, and not all spirits are entirely beneficial in nature. Focuses are completed over time; only one focus may be worked on at once, and working on one consumes some political power. Initially, only a handful of key nations, like Germany, the Soviet Union, and the United States, had unique focus trees; all other nations shared a generic one. Subsequent updates and DLCs have added focus trees to other nations as well.

Hearts of Iron IV also introduces the concept of "world tension," an abstract representation of how close the world is to war on a scale from 0 to 100. Aggressive actions by any nation can increase world tension, while peaceful actions can decrease it. Depending on the circumstances of a nation, like their ideology, a certain level of world tension may be necessary to perform certain actions, like justifying war against another country.

Development

At E3 2015, creative director Johan Andersson confirmed that the game would be pushed back from its original release window to the first quarter of 2016. This was an attempt to resolve several issues encountered with the game. In March 2016, it was announced that the game would be released on June 6, 2016, which is the 72nd anniversary of the Normandy landings.

Currently, the base game has a score of 83 from review aggregator Metacritic, translating to "generally favorable reviews".

GameSpot gave the game a positive review, writing that "Hearts of Iron IV embodies the hard truths about all-consuming war and the international politics that guide it." It argued that the tutorial was the only weak point, and that "for the dedicated, Hearts of Iron IV could end up being the best grand strategy game in some time."

It was also reviewed in Kotaku, with the reviewer writing it was "overwhelming in both its depth and, more importantly, its complexity," and arguing that some players unfamiliar with the franchise might find the game interface too complex to easily navigate.

IGN wrote a positive review, describing it as "an incredibly complex World War II simulation that will require potentially hundreds of hours to master, both in-game and poring over wiki articles that read like an economics textbook," but writing that "the payoff is brilliant for those willing to put in the time to learn." The review praised the layout, writing "thanks to an unusually striking look and clean, easily navigable interface, the biggest challenges Hearts of Iron 4 presents us with are the good kind: strategic planning, division composition, and fine-tuning economic and political policies." IGN went on to conclude that Hearts of Iron IV "is a strong contender for the title of ultimate armchair-general game. The biggest problems I can point to are almost all performance-related, putting a slow, frustrating finale on what is otherwise an ingeniously detailed strategic stimulation of just about every aspect of 20th-century global warfare."

A review in PC Gamer described it as a "unique, beautiful, thrilling wargame... while I found a number of flaws when I stood close to the tapestry, it's important to remember that Hearts of Iron 4 exists to encompass the whole sweep of the war."
