Integrated free into the base game, Death or Dishonor gave playable content to four Eastern European nations that until then were little more than pass-through territory for the great powers.
Nations and Content
Hungary, Romania, Czechoslovakia and Yugoslavia got their first focus trees of their own, with options to align with the Axis, the Allies, or more independent paths depending on the country.
What Changes
It introduced equipment conversion (adapting captured or outdated equipment to your current production lines), useful for small nations that rely more on what they get on the battlefield than on their own industry.
Is It Still Worth It?
Free of charge since it's integrated into the base game, it's a good way to get familiar with minor nations that are often ignored but can tip the balance depending on which side they end up on.
