In a bit of a strange move Paradox has just released two DLC packs for two of their most prominent grand strategy games. Europa Universalis IV has received Third Rome, a new "immersion pack" that adds a bunch of gameplay features and content for the Russian Empire, while Hearts of Iron IV has received Death or Dishonor, a new country pack that brings with it Romania, Czechoslovakia, Hungary, and Yugoslavia.

Individually each pack will set you back $10, but if you're a massive fan of grand strategy games and would like to grab both they can also be bought a slight discount, $18 to be specific. If you're wondering what exactly each of the packs bring to the table, here are their recently posted trailers and lists of features, starting with Hearts of Iron IV:

• 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.

Please note: Hearts of Iron IV: Death or Dishonor is included in the Expansion Pass #1 

• Tsardoms and Principalities: New ranks of Russian government with new abilities and, for Tsars, strong bonuses including the right to claim entire States – not just provinces.

• Iconography: Commission great religious icons for the Orthodox church, boosting your empire’s power depending on the saint you choose to revere.

• Metropolitans: Consecrate highly developed provinces with Metropolitans, adding to the authority of the Orthodox church, but for a cost.

• Streltsy: Special Russian soldiers that excel in combat, but raise the cost of stabilizing your empire.

• Siberian Frontier: Russian nations can slowly colonize uninhabited border regions, with no fear of native uprisings.
