Project Wilson is an alternate history mod, on steam and now mod DB, the steam link is here. even if you do not have the steam version you can access the link and mod page to see a better description for the mod
Project Wilson 5.0 includes a Hungarian Focus Tree, as well as a small one for Nepal, as the player chose if you will take Hungary down the path of conquest or down the path of communism? or maybe bringing democracy to the nation is your cup of tea, either way this update will let you.
is this supported by the 1.4.0 version of the game ?? and is there any mod for ship warefare
1. Yes
2. No clue, this isn't really the place to ask
