Hearts of Iron 4 has been around for a long time now, but the 2016 game is still continually being updated and expanded upon by its creators at Paradox Interactive, even as the developer/publisher continues to put out other strategy options like Stellaris, Crusader Kings 3, and Age of Wonders: Planetfall. With the huge number of DLCs made available for the game over the last eight years, it might be tough to figure out which ones are necessary for getting the most out of the experience. Luckily, Paradox is making that decision a whole lot easier right now by making three Hearts of Iron 4 DLCs free to claim.
