Research
Research is one of the Hearts of Iron 4 vanilla mechanics, for which the Old World Blues mod contains custom content.
Research is the priamry way of unlocking technologies, but some technologies can be obtained by completing a focus, or by a special event.
Research Slots
Technology is unlocked by assigning a research slot to it for the required number of days.
The base number of research slots depends on the country: Most generic nations and minor nations have 3 research slots with 2 more additional possible via national focus.
