Wayne Ligon reviewed issue #2 of
The Unspeakable Oath in
White Wolf #29 (Oct./Nov., 1991), rating it a 4 out of 5 and stated that "
The Unspeakable Oath is a top-notch magazine and I wish it a long life. Pick up this gem at once." In the November–December 1993 edition of
Pyramid (Issue #4), Chris W. McCubbin reviewed issues 7, 8, and 9 of
The Unspeakable Oath and gave the magazine a strong recommendation, saying, "The final assessment on
The Unspeakable Oath is simple — every gamer with an interest in
Call of Cthulhu (which means virtually every mature and intelligent gamer) should read this magazine religiously, and that's all there is to it." In the January 1994 edition of
Dragon (Issue #201),
Allen Varney was similarly impressed, saying, "Chaosium’s
Call of Cthulhu game (
CoC) has spawned the best one-game support magazine I’ve ever seen:
The Unspeakable Oath. This 80-page wonder crawls forth quarterly from Pagan Publishing, a small Columbia, Missouri company — more accurately, one talented and energetic guy named John Tynes." Varney praised the magazine's articles as "Fascinating features, columns, letters, and huge amounts of period source material (which is sorely lacking in Chaosium's own support for
CoC)." He also admired the artwork, "unsettlingly illustrated by
Blair Reynolds and others." Varney concluded that the magazine was "an Elder Godsend for both Keepers and players." The version of
The Unspeakable Oath by Arc Dream Publishing won the 2013 Silver
Ennie Award for "Best Aid/Accessory". In his 2023 book
Monsters, Aliens, and Holes in the Ground, RPG historian Stu Horvath noted, "
The Unspeakable Oath, launched in 1990, was indispensable for serious
Call of Cthulhu players and would eventually spawn
Delta Green." ==Reviews==
