  • AI and map scripts (AI/SCAR files)
  • Compiled FX files (BFX files; CoH only)
  • Locilized text (UCS files)
It also allows:
  • Loading and creating game data archives (SGA files)
  • Viewing and burning data generic unit stats (LUA files)
  • Creating and running RGD macros (LUA files)

Where to start

If you want to start modding, or want to learn how to mod using this tool, then the usage guide is the best thing to read through. Once you've understood this, you can start modding the best way - trying something and seeing what happens. Of course, it may be easier to check if the tutorials list has what you're interested in. If you cannot find it there, then the Relicnews CoH modding forum is where to ask your questions.
