HCl on Wing Commander 4 What kind of work has HCl done on Wing Commander IV? Good question--let's take a look! The Wing Commander Movie Player remains his most famous accomplishment; it lets players view any movie in the game! An FMV Audio decoder lets you "audio frames of WC4 FMV files." An Super Hellcat patch. And a Super Dragon patch (as if it needed that.) He has even imported a Darket!
