Okay I tried searching - couldn't find anything.
I've been trying to have a fiddle with the tech tree editor and I can't see how weapons work in it. Are they hard coded in?
I wanted to make a second path for each weapon type (A bullets path for mass drivers with lower dmg, cost and size, giant laser for beam weapons with higher cost dmg and size and a salvo path for missles with lower dmg higher cost but much much smaller). Is this possible or are weapons hard coded in?
