It's taken an age, but the Delta Green campaign source book for Call of Cthulhu is finally back in print. EOS Press, which is printing the book for Pagan Publishing, announced on their forums that the main shipment of books will arrive in December and should be available in January 2007. According to EOS' web site, the new edition is hardbound and has the traditional Basic Role-playing Game (BRP) stats and d20 stats compatible with the d20 version of Call of Cthulhu.
I'm sorely tempted to get it, even though I already have the original version, just to be able to run the d20 incarnation of the game. My own Delta Green campaign has been stalled for an age, and this could be the thing that gets it restarted.
