There is already a BHD game out, playable MP with some vehicles. The kill rate in the Mogadishu battle was about 50:1, so making an MP mod of it would be a disgrace IMO. To the modmakers: do something fictional and don't disrespect the people who died there, after all the amount of U.S soldiers involved was so relatively small that you're basically pretending to be individual soldiers you could name from the BHD book.
My 0.02€, and opinion on pretty much everything BHD except the book that sticks to the facts.
edit: aah
