D Day

Hello Everybody!

It's been now two years since the release of Hearts of Iron IV, Happy Birthday Paradox!
This day, is also the Anniversary of the D-Day, and we do not forget that there’s a graveyard in northern France where all the dead boys from D-Day are buried.

For this event, we've just released a new update, The Great War Mod Open Beta 0.5.3

As usual, to have a better view about the changes, a complete Changelog is available here:
Steamcommunity.com

To be noted that, as always, with or without Paid DLC, your gaming experience on The Great War will be very similar.
If you want to contribute to this great project, discuss, share your ideas, it's time to join us on GitHub: Github.com

Very promising mod you got here Wolf,can't wait to see how it will turn out.I understand that you are developing an interwar period too?
Will the timeline extend to WW2 as well?

Anyway,keep up the good work!

A great mod and I'd give it a 10 if it was finished. It's still technically is a 10, but some miner issues need to be worked around.
