Extended Timeline aims to extend the playable time in vanilla Hearts of Iron 4 while still keeping the vanilla fealing. The mod is a submod for the Ultimate Tech Tree : New Horizons. The mod extends the playable timeline by applying new Focus Trees and events based on the outcome of the second world war, these are called scenarios.
Scenarios are applied based on how the world state is at the end of the World War 2 and each playthrue can differ. You can read more about scenarios here.
