If we could get a .msh extractor updated for COD then there is a lot that could be done with this game.
As far as I can tell there is little difference between the old IL2 .msh format and the new one.* Its fairly easy to get aircraft from il2 into COD with a few lines added to the .msh header. But without an extractor it makes things a bit less fun. The MS 406 in IL2 is nice, but the model needs some work to meet COD standards
