There are some more functional features I'm not going into detail now and I may add more.
I've re-arranged the graphics so they can be fully painted (mostly). Decals use is very limited as the game only allows painting used tiles. There's a plethora of possible weapons many aren't too different so I'll add some variants and mostly the evolutionary ones. I've been thinking about tech levels but things are too blurred and shared so this is up to builders to keep to certain choices. I've added extra info that could help.
Currently, the mod is struggling with game bugs and related tests as well as scarceness of source material data. Frankly, important data don't exist at all. So there's a lot of unnecessary test code requiring clean up later. This could be a problem as some may survive into the release...
