The update has added new elements to the tech trees, additional decisions/events, previously unknown resources, and units. The project changes most of the game’s elements. We get a completely new map, previously unknown technologies and factions, as well as completely redesigned tech trees.
There is also a plethora of events to spice up the gameplay in the post-apocalyptic world destroyed by atomic war. Additionally, there are plenty of fresh visual and sound elements. In “Old World Blues,” we take part in a dynamic war between different factions known from the *Fallout* series.
They have all been meticulously recreated, receiving historical characters, their own units, and technologies. The mod is excellently developed. The authors have effectively managed to realize the post-apocalyptic reality while maintaining the depth of gameplay typical for *Hearts of Iron IV*.
Many modifications have been released for *HoI4*, but most of them only offer realistic historical scenarios. Projects that transport the action into fantastic realities are very rare, further increasing the attractiveness of *Old World Blues*. This year, a significant set of new units has been introduced, the list of events has been expanded, and the technological trees have been expanded.
