As I was working on version 4.0 and 5.0 and I thought "why don't I just combine these two and make a huge update!"
Here are a few things I am adding:
A new combat ship
2 new AIR units
A new infantry unit
A new heavy-armored unit
All civs have banks
Wagons can train units along with their building (a good way to quickly get troops onto the front)
All civs have war wagons
All civs have the Fluyt and the Galley
All civs have abus guns and organ guns
and many more things!
Version 4.0 is now TBA - hopefully sometime within the next few weeks
--- A Reminder ---
Modding can be very risky when you don't know what you are doing. Please, read the README.txt provided in the download for the installation instructions. I am not to blame for your ignorance. You have been warned!
