As a bit of a side note, here are some of the robot models created by users and posted on the doga website. They were originally for doga2 but this handy-dandy zip has them all converted to doga3. For all you lazy bastiches out there.
Doga3Bots.zip
Just decompress and then put the folder in DOGACGA->data->l3_samp->connection->human->robot folder
If you happen to reverse engineer any of these into some interesting Space Robots please post them so I might be able to finish my Giant Robot Mod.
