The Kingsport Metamorphosis: An Arkham Horror Investigators Gamebook

A mysterious letter summons you to the seaside town of Kingsport, where dreams leak into reality, to a wealthy estate transformed into a place of unspeakable nightmares in this new action-adventure gamebook set in the popular world of Arkham Horror.

A thrilling, if odd, request brings the Investigators of Arkham to the estate of wealthy recluse Elijah Harcourt in the mist-wreathed town of Kingsport. Curious to meet your mysterious host, your excitement is dashed when you discover Harcourt’s purpose is far more nefarious than you realized, leaving you and his guests with riddles to solve if you are to survive. As each hour passes, your companions meet terrible fates, forcing you to navigate a spiderweb of betrayal… Choose wisely, Investigator, for your dreams affect your sanity and the path you choose may lead you to a place of nightmares.

I have played a few of these Arkham Horror Investigators gamebooks now, and the main thing I noticed about them is how really, really hard it is to walk away alive. There are many endings, but almost all of them are bad. It makes sense; it’s a horror series after all. But still, I’d like to win at least some of the time.

Green seems to have got that complaint in The Kingsport Metamorphosis. It’s still a horror book, and most of the endings are still gruesome. But it felt like there were more nice ones in this book. I didn’t walk away from every read-through feeling depressed and hopeless, and that was nice. I actually “won” a few times. And that kept me excited to read it again.

I would definitely say that I returned to this one more times than any of the other Investigators Gamebooks that I’ve read so far. The re-readability makes The Kingsport Metamorphosis the best installment of the Arkham Horror Investigators Gamebooks to date and worth picking up.
