I've never played anything but 1920's Call of Cthulhu, and have never been to keen on the idea on modern-day CoC. But I must admit, the Delta Green campaign setting is really impressive. After having taken a look at it and purchasing it, I would recommend it to anyone who is looking for a change of pace in their CoC game. The best comparison I can think of is this: If CoC 1920's is the movie "Alien," Delta Green is the movie "Aliens." Both are cool, both have the same creatures as the adversaries, but they both have different moods and different types of protagonists. The background info in this book is so realistic, if I were a bit more mentally unbalanced :), I could easily believe every bit of it as gospel truth, not just a game setting.

Many have commented that DELTA GREEN is where X-Files meets the Cthulhu Mythos. They are correct, but it goes beyond that. Delta Green presents a satisfying and believable context for mythos roleplaying in the modern era. This supplement for CALL OF CTHULHU, a game which has a history of great supplements, raises the standard by which future works will be measured. This is quite possibly the best role-playing supplement ever. I have been into RPGs for nearly 20 years now, and I have seen most of what is out there. Believe me, it does not get better than this.

To call DELTA GREEN a supplement for Call of Cthulhu is to do it a great injustice. Even if you don't play the game, but are a Lovecraft aficionado, you owe it to yourself to pick this up and see what Tynes and company have done. This is not your father's Cthulhu Mythos. This is something much, much nastier.

Gone are the days where monsters lurked in dark places, and could be banished with the right spells. The stars are right - right here, right now, and the Mythos has kept pace with modernity, corrupting openly, though humanity is still too blind to see. Delta Green has been fighting them ever since Innsmouth and 1927, a hidden conspiracy within the government dedicated to seeking out and destroying that which threatens humanity.

Only trouble is, even the government has disavowed Delta Green, in favour of collusion with the enemy. But the menace is so great that Delta Green continues, an illegal conspiracy hidden in the bowels of that which wants too destroy it. Delta Green isn't Mulder or Scully, seeking the truth that nobody else knows. Delta Green *knows* the truth, and is making sure nobody else suffers from knowing that either.

DELTA GREEN takes everything we know about modern day conspiracy theory - Roswell, Area 51, Majestic-12, UFOs, and merges it seamlessly with the battle against the forces of the Cthulhu Mythos. The secret history it reveals is frighteningly plausible, and like Lovecraft's fiction, nags at you and makes you doubt its fictional qualities.

As a way of bringing a moribund CoC campaign from the gothic horror of the 1920s to the survivalist horror of the 1990s, it is second to none. Think you could have dealt with those creepy crawlies if you only had an AK-47 instead of a revolver? Think again. The psychological cost of fighting terrors from beyond is not forgotten either, with Delta Green agents wandering shell-shocked from encounter to encounter.

And as I said, as a means of stimulating your imagination to bring Lovecraft up to date, it is also superb. Anyone who thinks Lovecraft's themes are hackneyed and old only needs to read this to see how horrifyingly relevant they still are.

Buy this book, and its companion DELTA GREEN: COUNTDOWN, which describes the UK and Russian counterparts to Delta Green. The truth is here. And it's hungry.
