Currently there are no Campaigns even when you use the Destiny code. It looks like the Patches have delayed work on the mods, although I'm not clear on whether Bard or someone at Random house is writing the Mod.
I wouldn't worry Although the Physical book stated the code was on the inside Front cover it was actually on the inside back cover.
I haven't read the book yet, it's next far Charles Stross "The Jennifer Morgue". ( Part IT, Part James Bond, Part H.P. Lovecraft - the Laundry series is highly recommended - start with "The Atrocity Archives" , Then "The Jennifer Morgue" , "Wireless" )
