Getting a hold of Delta Green books has been something of an ordeal in recent years. Copies of the main Delta Green book, and Eyes Only can be found off of Arkham Bazaar (with rather egregious shipping). If one looked hard enough, and was unscrupulous enough to swipe books off of P2P, one could find a perfect copy of Targets of Opportunity, the latest sourcebook, and truly awful scans of the main Delta Green sourcebook and Delta Green: Countdown. But finding legal, reasonably priced hard or softcover of some of these books, particularly Countdown, has been well nigh impossible.
To put this in perspective, copies of the Hardcover 2007 (revised
with d20 Stats for the ill-fated d20 Call of Cthulhu) version of Delta
Green can be found new for $40 off of Arkham Bazaar. However, Delta
Green: Countdown, first published in 1999, has been a lot harder to find
in recent years...so much so that I paid $105 last year off of Ebay for
a mint condition softcover.
As a member of the Delta Green mailing list, I was very excited to get home today and learn that the much promised deal by Pagan Publishing and Arc Dream Publishing to get the existing print only Delta Green books into PDF format is live.
You can now pick up the first two Delta Green sourcebooks (Delta Green, and Delta Green: Countdown) off of RPG Now. They're apparently available in both PDF and Print On Demand.
Apparently work is afoot to get the rest of Pagan's back catalog, including the other two Delta Green Sourcebooks, Eyes Only and Targets of Opportunity, as well as some of their non-Delta Green Mythos offerings in the coming months available via PDF & POD shortly as well. Having never picked up Targets of Opportunity, I look forward to picking up a copy when it comes out.
It's also worth noting that the various novels and short fiction collections set in the Delta Green setting can also be found via PDF off of RPGNow as well.
If you're into Call of Cthulhu, and are at all intrigued by the Delta Green setting (which I did a review of earlier this month), check it out. You won't find a better deal, believe me.
