I recently returned to the game after a 5+ year hiatus. It seems like some of the maps are missing or out of date (or maybe I'm just dumb/blind and couldn't find the latest).
So I took a copy of the brewall in-game maps and converted them to seq format using the script at the top of this forum.
They can be downloaded here: https://github.com/burner2/brewall4s...ive/master.zip
