CommanderD has created a custom skin mod to put the Star Fox Adventures Krystal into a pixel-based action RPG game with heavy Japanese lore influences. The Krystal skin comes complete with her Staff as a weapon. This mod was designed in the Playstation 4 version of Cladun Returns: This is Sengoku!, but it should also work in the much cheaper Cladun X2 (both available on Steam).
To recreate this skin yourself, refer to the image gallery below. It shows how the various parts are constructed, pixel by pixel. Thanks very much for CommanderD making this available to us all.
