I've just stumbled on this, this is the type of game I've wanted for years! I watched your latest tutorial video on Youtube, I was getting different penetration results than yours, went back and double checked all the values, It may be due to the uploaded release not having armor quality.
Looking forward to seeing more editors, as well as a combat scene. I've already made multiple real-world receiver and calibers, using as much information publicly available, would love to see a place to share these! Any plans for an engine designer for Wheeled/Armor units? I could ask a million questions all day. Looking forward to the next update!
