Yes, I found that. Thank you!
My other question is, how would you mod that?
It doesn't look like the hook thing would be straitforward, since you have to convince the game engine to run your modified script alongside that one-but if you just copy the Units.lua script into hook/lua/sim and modify it there, it just messes things up since hook concatenates it onto the original.
Does anyone know where the core lua scripts for Engymod are stored? I know it was integrated into FAF-I want to see how it works.
