A huge expansion of Hearts of Iron IV, Darkest Hour is an ambitious historical immersion project that will place fate in the hands of the player. Start the game from 1933 onwards, and suffer through the tragedy of the 30’s once more, but this time, with the tools to challenge the predestined outcomes.

A complete overhaul of the game, the mod both expands upon existing mechanics and even adds new systems entirely. Hundreds of new events, decisions, and foci change the playing field entirely. Revamped cabinet positions, new laws, a dual leadership system and a parliament UI for all countries provides depth to the political arena while a currency system allows for closer economic management. The mod also possesses an all-new map that is both detailed and accurate while remaining aesthetically pleasing with a style akin to that of the original Darkest Hour.
