DANGER MAGNET! (
www.dangermagnet.com) has some FREE material for DESOLATION that they provided exclusively for the first issue of the PDF MAGAZINE.
The entire issue of DANGER MAGNET! is FREE, and whereas we don't have a review of DESOLATION until our 2nd issue (we needed to find someone that wasn't connected to DESOLATION in anyway to do our review), we do have a free article that explains a location, an NPC, and will shortly have three story seeds/plots/story hooks.
Possibly you could get a feel for the game from the article. Then again I am biased.
