I downloaded the client for a private server of Sudden Attack (Classic) and all the character files seem to be inside these .lpk files. Is there a way to extract what's inside? I believe the game uses Lithtech engine if that helps. I have tried using aluigi's bms scripts but they don't seem to work on these files?

upload a few samples to an external source and send the link

I put up 3 different packages above. First one should contain characters, second seems to have textures for something (?), and the third was located in the "store" folder so maybe characters as well?
