  • Truly fantastic

    — Diehard Gamefan, Horror on the Orient Express Review - Digital Edition Review.

  • "The biggest and most grandiose campaign ever composed for any game… a must-own campaign. It is not just the grandeur, the scope, the high-quality writing or the fact that it epitomizes many of the values of Call of Cthulhu and the horror genre overall. It is the sheer immersion, the entertainment value it provides when played to the level it deserves…

    — Antonios S., RPGNet Review.

  • "I am pretty confident that this is the best Call of Cthulhu campaign Chaosium has ever produced... The thought and work that went into this turned a pretty good campaign into an epic one. I truly cannot think of anything that rivals it in scope."

    — Vintage RPG, Horror on the Orient Express Review.

  • "The most ambitious Call of Cthulhu adventure ever created… a high water mark for CoC."

    — Black Gate, Horror on the Orient Express Review.

  • "A must-own campaign"

    One of the best TTRPG campaigns I have ever played

    Posted by MC on 14th May 2023

    Just finished the Orient Express campaign as a Keeper after several months of playing. It was very easy to follow, the book contains lots of contingency scenarios and alternative choices that had me covered when the players made choices that the campaign did not consider - it was easy to get back on track. Both me and players had lots of fun. I think it was the best TTRPG campaign I ever played.
