Alone Against the Wendigo

Alone Against the Wendigo, subtitled "Solitaire Adventure in Canada's Wilds", is a solo adventure published by Chaosium in 1985 for the horror role-playing game 
"Call of Cthulhu". 
Description.
Plot summary.
"Alone Against the Wendigo" is a "Call of Cthulhu" adventure for a single player, with no need for a referee. The player takes on the role of Dr. L. C. Nadelmann, an anthropologist from Miskatonic University. The doctor, accompanied by a local Métis guide and three graduate students, travels deep into the wilds of Canada, seeking the mysterious North Hanninah valley. The doctor and companions will face many challenges, including an encounter with the Wendigo.
Gameplay.
Blank Investigator sheets are provided. After choosing Dr. Nadelmann's gender, the player must then choose how to allocate 390 skill points, with at least 40 going towards Anthropology.
The player starts the adventure by reading the first paragraph of the adventure. All of the subsequent 654 paragraphs are individually numbered; much like the "Fighting Fantasy" series of adventure books published by Games Workshop, decisions made by the player, or succeeding or failing at luck, combat or skill dice rolls, will route the player to different paragraphs, providing a varying storyline depending on the choices, successes and failures the player makes.
At the end of each paragraph, the player is rewarded with a certain number of "Hanninah Mythos" ("HM") points, representing the knowledge the doctor has learned.
Victory conditions.
The player can consider the game won if the doctor defeats the Wendigo, returns with all his party members alive, and is in possession of 
Replays.
The same player can replay the adventure over again to see what different decisions and successes or failures have on the storyline. If the doctor dies, the player can restart, the only requirement being that Dr. Nadelmann's skill points must be reallocated, and the doctor will only be credited with 1/5th of the HM points that the previous doctor earned before he died. If Dr. Nadelmann survived but only scored a partial victory, the player can send the doctor out into the wilderness again with the same character sheet and full accumulated HM points as well as renewed vigor, sanity and constitution scores. 
Publication history.
Chaosium originally published the horror role-playing game "Call of Cthulhu" in 1981. "Alone Against the Wendigo", published in 1985, was the game's first solo adventure, a 68-page softcover book with a removable cardstock insert designed by Glenn Rahman, with contributions by Jeff Okamoto, and artwork by Dan Day, David Day, and Tom Sullivan. 
"Alone Against the Wendigo" was quickly followed by a second solo adventure, "Alone Against the Dark" (1985).
Twenty years after its initial publication, "Alone Against the Wendigo" was rewritten and updated to 7th-edition "Call of Cthulhu" rules by Gavin Inglis, with interior artwork by Albert Bierstadt, Quinn Dombrowski, Gnangarra, Gavin Inglis, Caleb Kimbrough, Alfred Pearson, and William Warby, and cover art by Petr Štovik. It was retitled "Alone Against the Frost" to avoid the cultural appropriation of "Wendigo", a significant term in some First Nations cultures.
Reception.
In the April 1986 edition of "White Dwarf" (Issue #76), Phil Frances noted that ""Wendigo" is [...] written in a style likely to enhance enjoyment." But he cautioned that "The adventure is very tough, and one game can be totally different from the last (although there are certain constant elements), so this is one solo that can be played over and over again. The possibilities are not easily exhausted, and it is a real challenge trying to succeed." Frances criticized the addition of Hanninah Mythos points, pointing out "the addition of Hanninah Mythos after each paragraph can break the action up, spoiling the atmosphere." He concluded by giving it an overall rating of 8 out of 10, saying, "The solo format works well for "Call of Cthulhu", and I know that another such adventure is soon to be released. With a bit of luck, it won't be the last."
In the April 1986 edition of "Adventurer" (Issue 1), the reviewer found the adventure very challenging, noting, "Beset with mishap, misfortune or disaster from the start, you will need skill and luck to survive this adventure. Two failed skill rolls could result in the death of the whole party by the 4th paragraph, whilst a few more failed rolls could end up with the loss of the party, and with Dr. Nadelmann discredited, imprisoned and hated. All this without so much as an encounter with a wild animal!!" The reviewer concluded with a recommendation, saying, "It can be used over again and then possibly modified to be run as a group adventure, making it worth adding to your collection of "Cthulhu" regalia."
