Not yet ... 5pm E.T today if everything goes as planned.
From DJ's FB page:
Hey folks, testing continues. The map is set to RELEASE tomorrow, Friday, April 1st, 2022. Don't worry it's not an April Fools joke. It will be available on my itch.io page and also in FB posts around 5PM EST. https://djmodding.itch.io/
I will also be releasing my edit of base game trailers (mod) to carry Anhydrous and Propane, although there might be some great mods around. Sorry to tease you a lot, It gonna be Available Tomorrow. This map is Green Valley Nebraska. It's for PC only and 4X map.
