There are tools available for opening .4ds files of H&D2 in 3ds Max. Have a look at my thread @ hidden-and-dangerous.net. I’m currently working on a new version of an editor which allows editing of most files found in H&D2, including scene2.bin and collisions. Maybe I’ll try to adapt this one for Mafia and Chameleon, too, if someone needs that.

Unpacking of Chameleons .dta files is possible. I’ve recently developed an unpacker which is able to unpack both ISD0 and ISD1 archives. I’ll release it soon.
