Reviews

“Hearts of Iron 4 wields complexity like a swift armor division during the blitzkrieg, allowing it to serve the idea of layered, cerebral, strategic warfare instead of letting it needlessly bog down the experience.”
9/10 – IGN

“It captivates me because—imperfectly, impressionistically, and perhaps a little amorally—it lets me orchestrate the most titanic armed struggles in history, from the fussy economic details to the cut-and-thrust of mechanized warfare. There are other great strategic-level wargames out there. But I have never played anything like Hearts of Iron 4”
8.8/10 – PC Gamer

“For now, after many dozens of hours, I'm taking a break from Hearts of Iron 4. Not because I'm sick of it; quite the contrary, in fact. What I need to do is some serious reading, some careful planning on what my vision for the United States should be in 1936. And when I've done that planning — when I've formulated my character sheet, as it were — I have the utmost confidence that Hearts of Iron 4 will be ready for me to play a role in world affairs.”
8/10 – Polygon

Death or Dishonor!

Death or Dishonor is a new Country Pack for Hearts of Iron IV, and expands upon players’ ability to experience history’s greatest conflict from any point of view. This new pack focuses on the countries caught between the Soviet Union and Nazi Germany during World War II -- faced with the tough choices of starting a conflict with a global superpower or compromising their ideals to strike a deal for their own survival.

Including new National Focus Trees for Hungary, Romania, Czechoslovakia, and Yugoslavia, Death or Dishonor adds new unique events, nation-specific art and music, and much more, giving players all-new ways to experience -- and change -- the course of history.

Death or Dishonor includes:

Four New Focus Trees:

Experience the war from the difficult perspectives of Hungary, Romania, Czechoslovakia, and Yugoslavia.

Equipment Conversion:

Update your arsenal by converting older units -- or make use of captured enemy vehicles and gear.

New Music and Art:

3 new thematic musical tracks from composer Andreas Waldetoft, new art content for the four focus nations, and new troop voiceovers.

New Diplomatic and Puppet Interactions:

License military technology to bring other nations’ weapons to the field or sell your advances to the highest bidder. Fascist countries get new subject levels like Reichskommissariat, with access to licenses, industry and strategic resources. The instated governments are held in an iron grip, making it harder for them to break free.
