I'll help with buttons. I haven't done much with civics but I'll give it a try.I'll help with other XML like civs if you want to add more but it looks like all you need to do for civs is adding leadherheads. I'll help with static leadheads if you want, not moving 3d ones. I'll help with most XML though. Do you think I should use the units in the original mod and add them to the BTS mod?
