Cadian 113th Shock Troops
First off we have a blog by Cundo, who was kind enough to submitted a pic for the Narrative Campaigns PDF. Currently there's a node campaign running based on a map published in White Dwarf a few years ago. If you look further back, you'll also find a few small map campaigns based GW's plastic hex map pieces. It's well worth a look, especially some of Cundo's combination artwork pictures.
Next up, we have a dedicated campaign blog based on a digital hex map. It's earlier days in the campaign, but the map, the general graphics and the background is truly excellent and well worth checking out. I'd love to know how the map was created, may I can get the creator to do us a tutorial, if I can figure out how to contact them. In the meantime, check it out, it's very inspiring.
