The GR2 Editor/Viewer is not complete yet and thus we are still unable to create new GR2 files from scratch and we are still unable to add/remove geometry to/from GR2 files (the current test version being used by testers allows geomtry to be changed though). Once I complete it everything will be possible.
Now that doesn't mean that one will be able to add new playable subs into the game. That will require an exe patch so that the game knows about these new subs
And that will take time to do....lots of time
