Place all agent files into your C3/DS "My Agents" folder.

To install the alternate winged arm sprites, copy the "Images" and "Body data" folders from the "Draconian arm wings" folder and merge them with your C3/DS folders of the same name. To revert the changes, do the same but with the contents of the "Original" folder.
